This document discusses object-oriented programming concepts in Kotlin such as classes, objects, methods, and static methods. It provides examples of defining classes that represent real-world entities like cars. Objects are defined as instances of classes that contain an address and occupy memory. Methods are functions that are part of a class and can be invoked by objects. Static methods belong to a class rather than individual objects.
This document provides an overview of object-oriented programming concepts in Java including inheritance, polymorphism, abstraction, and encapsulation. It also discusses control structures like if/else statements and switches as well as repetition structures like while, do-while, and for loops. Arithmetic operations in Java like addition, subtraction, multiplication, and division are also mentioned.

The document discusses key concepts in object-oriented programming in Java including classes, objects, inheritance, packages, interfaces, encapsulation, abstraction, and polymorphism. It provides examples to illustrate each concept. Classes define the structure and behavior of objects. Objects are instances of classes. Inheritance allows classes to extend existing classes. Packages organize related classes. Interfaces define behaviors without implementation. Encapsulation hides implementation details. Abstraction models essential features without specifics. Polymorphism allows the same method name with different signatures or overriding.
The document provides an introduction to object-oriented programming concepts. It discusses how OOP models the real world using objects that have both state in the form of attributes, and behavior through methods. Some key advantages of the OOP paradigm include simplicity through modeling real-world entities, modularity by encapsulating data and behavior within classes, and reusability through inheritance. The document outlines important OOP concepts such as classes, objects, encapsulation, inheritance, polymorphism, and abstraction.

Java is an object-oriented programming language created in 1991 by James Gosling at Sun Microsystems, which was later acquired by Oracle Corporation. It uses concepts like encapsulation, inheritance, polymorphism, and abstraction to simplify software development and maintenance. Object-oriented programming creates objects that contain both data and behaviors to model real-world entities like chairs, pens, and computers. Classes are blueprints that define objects, while objects are specific instances of classes that occupy memory.
The document discusses object-oriented programming concepts like inheritance, subclasses, and polymorphism. It provides examples of different forms of inheritance including:
1. Inheritance for specialization where a child class is a specialized form of the parent class and the principle of substitutability holds.
2. Inheritance for specification where a parent class specifies behavior but doesn't implement it, and child classes implement the behavior, like with interfaces and abstract classes.
3. Inheritance for construction where a child class inherits functionality from a parent but may change method names/parameters, primarily for code reuse rather than creating a subtype relationship.
This document discusses the basic concepts of object-oriented programming (OOP), including data abstraction, encapsulation, modularity, inheritance, polymorphism, and the relationships between classes. It explains that OOP aims to overcome the drawbacks of conventional programming by basing the approach on these concepts. Some advantages of OOP include reusability of code, ease of understanding due to representing real-world concepts, and easier modification, while disadvantages include potential overgeneralization of classes and difficulty of design.

How would you implement multiple inheritance in javaTyagi2636
Java does not support multiple inheritance to avoid complexity and ambiguity problems. Interfaces were introduced instead, allowing a class to represent different structures by implementing multiple interfaces. In C++, multiple inheritance can cause ambiguity errors at runtime if two parent classes define the same method. Java's single inheritance with interfaces avoids this problem by not allowing method implementations in interfaces, so there is only one implementation per method.
This document provides an overview and summary of various C# programming concepts including modules, for loops, enums, classes, inheritance, static, arrays, dictionaries, error handling, interfaces, abstract classes, delegates, and examples of using these concepts. It discusses good practices for creating classes and variables as well as examples demonstrating sorting arrays, using dictionaries and interfaces, handling exceptions, overriding abstract classes, and using delegates through examples like a media tester program.
The document discusses key concepts in object-oriented programming (OOP) including objects, classes, encapsulation, inheritance, polymorphism, and message passing. It provides examples of a simple class named "item" that includes variables and methods. It also discusses how objects are composed of data and functions, and how classes are used to organize data and functions through principles like private/public access and data abstraction.
Classes, objects, methods, constructors, this keyword in javaTharuniDiddekunta
The document discusses classes, objects, methods, constructors and the this keyword in Java. It defines that a class is a blueprint for objects and contains variables and methods, while an object is an instance of a class with state and behavior. It provides examples of creating a class with data members and methods, and then creating objects of that class. The document also covers access modifiers, different types of constructors like default, parameterized and overloaded constructors. It explains the differences between methods and constructors.
This document discusses inheritance in object-oriented programming. It defines inheritance as allowing code reuse through classes inheriting traits from parent classes. The document covers different types of inheritance like single, multi-level, multiple and hierarchical inheritance. It also discusses inheritance in various programming languages like C++, Java, Python and ADA. The advantages of inheritance are code reuse and extending parent classes without modifying them, while disadvantages include subclasses being brittle and inheritance relationships not changing at runtime.
The document discusses abstract classes and concrete classes in Java. It defines an abstract class as a class marked with the abstract keyword that can contain abstract methods without an implementation. Concrete classes must implement the abstract methods and provide a basic implementation. The document includes an example abstract class program and concrete class program to demonstrate the relationship between the two, where the concrete class inherits from and implements the abstract class.
This document discusses inheritance in object-oriented programming. It defines inheritance as establishing a link between classes that allows sharing and accessing properties. There are three types of inheritance: single, multilevel, and hierarchical. Single inheritance involves one parent and one child class, multilevel inheritance adds intermediate classes, and hierarchical inheritance has one parent and multiple child classes. The document provides examples of inheritance code in Java and demonstrates a program using inheritance with interfaces. It notes some limitations of inheritance in Java.
This document discusses some of the problems that can arise with multiple inheritance in object-oriented programming, including name ambiguity when classes have methods with the same name, issues with inheritance from common ancestors, and how inner classes can provide an alternative to multiple inheritance without the same semantic problems. It provides examples and potential solutions to demonstrate these problems.
The document discusses the implementation of object-oriented programming concepts in C++ using classes. It defines what a class is, how to declare objects of a class, access members of a class using dot operators, and define member functions inside and outside the class. It also covers topics like static members, inline functions, constant member functions, nested classes, and passing objects as function arguments.
The document discusses friend functions and friend classes in C++. A friend function has access to all private and protected members of a class but must be called with an object passed as a parameter rather than through an object. A friend function violates data hiding and encapsulation. A friend class allows member functions of one class to access private members of another class, providing similar functionality to a friend function but through class members instead of standalone functions. Code snippets demonstrate declarations of friend functions and classes.
Abstract classes allow for incomplete implementations and common functionality to be shared among subclasses, interfaces define a contract for methods without implementations, and both are useful for abstraction and polymorphism by defining types independently of their concrete implementations.
This document discusses different programming paradigms and object-oriented programming concepts in C++. It defines procedural programming as step-by-step instructions telling a computer what to do, with languages like C, Go, and BASIC given as examples. Modular programming is described as separating a program into independent modules. The difference between procedural and modular programming is that procedural follows an algorithm, while modular divides the objective into pipelined modules. Object-oriented programming concepts covered include objects and classes as logical entities, encapsulation as wrapping data and methods, abstraction as exposing only essential characteristics, inheritance as creating new classes from existing ones, and polymorphism as having many forms in a hierarchy with inheritance.
This document discusses object-oriented design principles including encapsulation, abstraction, inheritance, polymorphism, and decoupling. It then introduces the SOLID principles of object-oriented design: single responsibility principle, open/closed principle, Liskov substitution principle, interface segregation principle, and dependency inversion principle. Code examples are provided to demonstrate how to apply these principles and improve code maintainability, reusability, and testability.
The document discusses the basic concepts of object-oriented programming including classes, objects, inheritance, polymorphism, encapsulation, and data abstraction. It defines a class as a structure that contains common data and functions to represent objects, and an object as an instance of a class that has attributes, state, and behavior. The document provides examples of how classes can be used to represent objects like students and rectangles, including defining class structures with attributes and methods.
This document provides an introduction to general object-oriented programming concepts. It discusses that OOP offers a powerful way to develop software by creating objects that encapsulate both data and functions. The core concepts of OOP explained are objects, classes, encapsulation, inheritance, polymorphism, and message passing. Objects communicate by sending and receiving messages, and classes act as templates for creating object instances that share common properties.

The core concepts of OOP explained are objects, classes, encapsulation, inheritance, polymorphism, and message passing. Objects communicate by sending and receiving messages, and classes act as templates for creating object instances that share common properties.
Object-oriented programming uses objects to represent real-world entities. An object has state, which describes its characteristics, and behaviors, which are its capabilities. A class defines a blueprint for objects and multiple objects can be created from the same class. Objects encapsulate both data and functions that operate on that data.
OOP concepts include classes, objects, methods, encapsulation, inheritance, and polymorphism. A class acts as a blueprint that defines properties and behaviors of an object. Objects are instantiated from classes and can have different property values. Methods define object behaviors. Encapsulation bundles data and methods into a class and hides implementation details. Inheritance allows subclasses to inherit properties and behaviors from parent classes. Polymorphism enables the same method to process different types of objects.
Basic concepts of object oriented programmingSachin Sharma
This document provides an overview of basic concepts in object-oriented programming including objects, classes, data abstraction, encapsulation, inheritance, polymorphism, binding, and message passing. Objects are run-time entities with state and behavior, while classes define the data and behavior for objects of a similar type. Encapsulation binds data and functions within a class, while inheritance allows new classes to acquire properties of existing classes. Polymorphism enables one function to perform different tasks. Binding determines how function calls are linked, and message passing allows objects to communicate by sending requests.

The document discusses key concepts in object-oriented programming including objects, classes, messages, and requirements for object-oriented languages. An object is a bundle of related variables and methods that can model real-world things. A class defines common variables and methods for objects of a certain kind. Objects communicate by sending messages to each other specifying a method name and parameters. For a language to be object-oriented, it must support encapsulation, inheritance, and dynamic binding.
The document discusses the Calendar and GregorianCalendar classes in Java. It provides details on their constructors, methods, and usage. Calendar is an abstract class that provides methods for converting between a date and calendar fields like year, month, etc. GregorianCalendar is a concrete subclass that implements the standard Gregorian calendar system. It supports both the Julian and Gregorian systems and handles leap years according to Gregorian rules. Examples are provided to demonstrate using these classes.
This document describes how to create a calendar application in Java using Swing. It discusses using the Calendar, GregorianCalendar, and Timestamp classes to work with dates. The application displays a calendar with previous and next buttons to change months, and a combo box to select years from 100 years ago to 100 years in the future. It covers creating Swing GUI components like JFrame, JLabel, JButton, adding them to containers and registering action listeners. The calendar is rendered in a JTable with weekends highlighted in red and the current date in blue.
object oriented programming(syed munib ali 11b-023-bs)munibali55
The document discusses object-oriented programming (OOP) by defining its key concepts like class, object, inheritance, encapsulation and polymorphism. It explains the advantages of OOP over traditional procedural programming in building complex software through reuse, maintenance and extensibility. Examples are provided to illustrate OOP concepts like defining classes for entities like humans and mobiles, creating objects, inheriting properties and using encapsulation.
A parameterized constructor is a constructor that has parameters and is used to provide different values to distinct objects by allowing values to be passed into the constructor. Parameterized constructors are useful for initializing objects with different initial values without having to use setter methods after object creation.
This document discusses the basic concepts of object-oriented programming (OOP). It defines objects as instances of classes, and classes as user-defined data types that contain variables and functions. It describes data abstraction and encapsulation as wrapping data and functions into a single class unit. Other key concepts covered include inheritance, polymorphism, dynamic binding, and message passing. Benefits of OOP like reusability and mapping to real-world objects are highlighted. Real-time systems, databases, and modeling are some example applications of OOP.
The document discusses object-oriented programming concepts like objects, classes, encapsulation, inheritance and polymorphism. It provides examples of how real-world entities like a dog, car etc. can be modeled as objects in code with their state represented by variables and behavior by methods. A class defines the common properties of objects and acts as a blueprint from which individual objects are created. Encapsulation binds data and methods operating on that data within an object. Polymorphism allows the same message to be interpreted differently by different objects through operator and function overloading.
This document discusses polymorphism in C# through method overloading and overriding. It shows how to create a base DrawingObject class that can be inherited by Line, Circle, and Square classes, where each subclass overrides the Draw method to output its type. The Main method creates instances of each subclass and calls their Draw methods to demonstrate polymorphism. The document also compares abstract classes and interfaces, noting that abstract classes can contain implemented methods while interfaces only contain signatures, and interfaces allow multiple inheritance while abstract classes do not.
This document discusses object oriented design principles including minimizing accessibility of classes and members, favoring composition over inheritance, programming to an interface rather than an implementation, the open-closed principle of being open for extension but closed for modification, and the single responsibility and Liskov substitution principles. It also provides references and contact information for Sayed Ahmed, owner of Justetc Technologies, which provides consulting services in software development, web development, and other areas of IT and computer science.
This document discusses key concepts in object-oriented programming including classes, objects, methods, abstraction and encapsulation, inheritance, and polymorphism. It defines a class as a user-defined data type that includes attributes. An object is an instance of a class that has behaviors, holds information, and can interact with other objects. A method defines the behavior of an object. Abstraction and encapsulation involve hiding details and binding data and functions together. Inheritance allows a class to acquire properties of its parent class. Polymorphism allows different behaviors in different instances.
The document provides an overview of the Open Verification Methodology (OVM) framework. OVM is a SystemVerilog library that implements object-oriented design patterns to provide base classes for verification components. It includes features for component hierarchy, configuration, phasing, reporting, transaction recording, and interfaces based on the Open System C Initiative Transaction Level Modeling 2.0 standard.
An interface in Java is a blueprint of a class that defines static constants and abstract methods. Interfaces are used to achieve abstraction and multiple inheritance in Java. An interface cannot have method bodies and can only contain abstract methods and variables that are public, static, and final by default. Classes implement interfaces to inherit their methods. Since Java 8, interfaces can also contain default and static methods.
The document outlines the course units for an Advanced Java Programming course. Unit 1 covers classes, interfaces, inheritance and encapsulation. Unit 2 discusses methods, method overloading, overriding and recursion. Unit 3 focuses on exceptions, threads and immutability. Unit 4 covers dynamic language support and APIs. Unit 5 is about Java annotation processors and agents.
Object Oriented Concepts required to know about the Android Application Programming are discussed over here. Get the most of the details about each and every concept of OO paradigm so you can use them very well in Android Application Programming.
1. The document discusses Java concepts like serialization, reflection, JDBC, and distributed applications.
2. Serialization allows saving object state to a file by implementing the Serializable interface. Reflection obtains runtime information about classes.
3. JDBC is used to connect to databases and store data permanently. Distributed applications run across a network and allow for data sharing between clients.
1. The document discusses Java Database Connectivity (JDBC) and serialization in Java. JDBC is a specification that allows Java programs to store data in databases. Serialization is the process of saving an object's state to a file.
2. To develop a serializable subclass, a class must implement the Serializable interface and include getter and setter methods for its fields. An object of this subclass can then be written to a file using ObjectOutputStream.
3. Deserialization reads an object back from a file using ObjectInputStream and reconstructs it in memory from its stored state.
This document discusses inheritance and polymorphism in Java. It begins by introducing the motivations for inheritance, which is to avoid redundancy when designing classes that share common features, like circles, rectangles, and triangles. It then lists the chapter objectives, which include defining subclasses, invoking superclass constructors and methods, overriding methods, polymorphism, and other inheritance-related concepts. The document provides an example of superclass GeometricObject and subclasses Circle and Rectangle. It also discusses that superclass constructors are not inherited by subclasses but must be invoked explicitly or implicitly using the super keyword.

Introduction of Object Oriented Programming Language using Java. .pptxPoonam60376
The slide contains the Introduction of Object Oriented Programming Language using Java. It covers basics of OOP, Inheritance,Polymorphism, Exception etc.
This document discusses classes, methods, objects, constructors and other object-oriented programming concepts in Java. Some key points:
- Classes are templates that define objects, while objects are instances of classes that have state and behavior.
- Methods are collections of code that perform specific tasks and provide reusability. The main() method is important as it is executed first.
- Constructors initialize objects and are automatically called when objects are created. There can be default and parameterized constructors.
- Objects are created using the new keyword and access class members like methods using the dot operator. Arrays can store multiple objects.
- Methods and constructors can be overloaded when they have the same name but different parameters
Abstract classes allow for defining a generalized superclass that leaves implementation details to subclasses. An abstract class can define methods that subclasses must implement. Abstract classes cannot be instantiated and exist solely to be extended. Interfaces define behaviors and properties but leave implementation to classes that implement the interface. Abstract classes can contain both abstract and concrete methods while interfaces can only contain abstract methods. Both allow for achieving abstraction and multiple inheritance in Java.
This document discusses object-oriented programming concepts including objects, classes, inheritance, polymorphism, abstraction, and encapsulation. It provides examples of how each concept is implemented in Java, including code snippets demonstrating classes, inheritance between classes, method overloading and overriding, and abstract classes. The key advantages of OOP such as code reusability and modularity are also summarized.
The document discusses Java programming concepts of exception handling and multithreading. It covers exception types, try/catch/throw/throws/finally clauses, creating custom exceptions, and the Java thread model for creating and synchronizing threads. The document also provides example code and discusses checked and unchecked exceptions, nested try blocks, and inter-thread communication in Java.

This document discusses object-oriented programming concepts in Java like abstraction, abstract classes, interfaces, method overriding and overloading. It provides examples of using abstract classes and interfaces to achieve abstraction and multiple inheritance in Java. Key points covered include how abstract classes can contain abstract methods that subclasses must implement, how interfaces provide a blueprint of methods without implementations, and how interfaces allow for multiple inheritance by allowing a class to implement multiple interfaces. The document also discusses access modifiers and packaging classes in Java which will be covered in the next session.
The document provides an overview of advanced programming concepts in Java including object-oriented programming (OOP) concepts, arrays and collections, exceptions handling, and multithreading. It discusses OOP concepts like classes, objects, abstraction, encapsulation, inheritance, and polymorphism. It also covers array and collections like Array, ArrayList, List, and Set. Finally, it briefly mentions exceptions handling techniques like try-catch and multithreading in Java.

Global and local alignment (bioinformatics)Pritom Chaki
A general global alignment technique is the Needleman–Wunsch algorithm, which is based on dynamic programming. Local alignments are more useful for dissimilar sequences that are suspected to contain regions of similarity or similar sequence motifs within their larger sequence context.
Transmission media (data communication)Pritom Chaki
Transmission media is the material pathway that connects computers, different kinds of devices and people on a network. It can be compared to a superhighway carrying lots of information. Transmission media uses cables or electromagnetic signals to transmit data.
The Open Systems Interconnection model (OSI model) is a conceptual model that characterizes and standardizes the communication functions of a telecommunication or computing system without regard to their underlying internal structure and technology. Its goal is the interoperability of diverse communication systems with standard protocols. The model partitions a communication system into abstraction layers. The original version of the model defined seven layers.

This is part 1 of my Java Learning Journey. This Contains Custom methods, classes, constructors, packages, multithreading , try- catch block, finally block and more.
3. PRINCIPLES
Encapsulation:
Mechanism that binds code and the data together and keeps both safe from outside
interference and misuse.
Inheritance:
the process by which one object acquires the properties of another object.
Polymorphism:
One interface, multiple methods.
4. EXAMPLES
Encapsulation:
public class Student{
private String name;
public String getName(){
return name;
}
public void setName(String name){
this.name=name
}
}
class Test{
public static void main(String[] args){
Student s=new Student();
s.setname("vijay");
System.out.println(s.getName());
}
}
5. EXAMPLES
Inheritance:
class Employee{
float salary=40000;
}
class Programmer extends Employee{
int bonus=10000;
public static void main(String args[]){
Programmer p=new Programmer();
System.out.println("Programmer salary is:"+p.salary);
System.out.println("Bonus of Programmer is:"+p.bonus);
}
}
7. ABSTRACTION IN JAVA
Abstraction is a process of hiding the implementation details and showing only
functionality to the user.
Ways to achieve Abstraction:
Abstract class
Interface
8. Abstract class:
A class that is declared as abstract is known as abstract class. It needs to be extended
and its method need to be implemented.
Example: abstract class Bike
{
}
Abstract method:
A method that is declared as abstract and does not have implementation is known as
abstract method.
Example: abstract void run( );
9. Example: ( Abstract class )
abstract class Bike{
abstract void run();
}
class Honda4 extends Bike{
void run(){
System.out.println("running safely..");
}
public static void main(String args[]){
Bike obj = new Honda4();
obj.run();
}
} ref: http://www.javatpoint.com/abstract-class-in-java
10. INTERFACE IN JAVA
An interface in java is a blueprint of a class.
It has:
Static constants
Abstract methods
Reasons to use:
Achieve fully abstraction
To support the functionality of multiple inheritance
To achieve loose coupling
12. EXCEPTION & EXCEPTION HANDLING
Exception is an abnormal condition.
In java, exception is an event that disrupts the normal flow of the program. It is an
object which is thrown at runtime.
Examples:
ArithmaticException
NullPointerException
NumberFormatException e.t.c
And the process we use to handle those exceptions is called
Exception handling.
13. KEYWORDS
We use five keywords to handle exceptions in java:
Try
Catch
Finally
Throw
Throws
14. General form of an exception-handling block:
try {
// block of code to monitor for errors
}
catch (ExceptionType1 exOb) {
// exception handler for ExceptionType1
}
catch (ExceptionType2 exOb) {
// exception handler for ExceptionType2
}
finally {
// block of code to be executed after try block ends
}
15. Thank you everybody !!!
Have a Good Day!
