The document discusses different types of control statements in Java programming including selection statements (if/else, switch), iteration statements (for, while, do-while), and jump statements (break, continue, return). Examples are provided for each type of statement to illustrate their usage in loops and conditional execution. Selection statements allow a program to choose different paths of execution based on variable values or expressions. Iteration statements allow code to repeat execution. Jump statements allow skipping the rest of the current block and transferring control elsewhere.

Inheritance in Java allows classes to inherit properties and behaviors from parent classes. This allows code reusability and method overriding to achieve runtime polymorphism. There are three types of inheritance in Java: single inheritance where a class inherits from one parent class, multilevel inheritance where a child class inherits from another child class, and hierarchical inheritance where multiple classes inherit from a single parent class.
This document discusses functions in C++. It defines what a function is and explains that functions are the building blocks of C++ programs. Functions allow code to be reused, making programs easier to code, modify and maintain. The document covers function definitions, declarations, calls, parameters, return types, scope, and overloading. It also discusses local and global variables as well as pass by value and pass by reference.
Learn the various forms of polymorphism in Java with illustrative examples to explain method overloading(Compile-time polymorphism) and method overriding(Run-time polymorphism)
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.

Access Modifiers in Java / Visibility Modifiers in Java
1. Default access modifier
2. private access modifier
3. protected access modifier
4. public access modifier
The document discusses modular programming in C. Modular programming involves breaking a large program into smaller sub-programs or modules. This makes the program easier to use, maintain and reuse code. Functions are a key part of modular programming in C. Functions allow breaking a program into reusable modules that perform specific tasks. Functions can be called anywhere in a program to perform tasks without rewriting code. Modular programming improves readability, reduces errors and makes programs easier to maintain and modify.
Polymorphism in Java allows an object to take on multiple forms. There are two types of polymorphism: compile-time polymorphism (method overloading) and runtime polymorphism (method overriding). Method overloading involves methods with the same name but different parameters, while method overriding involves subclasses providing their own implementation of a superclass method. Runtime polymorphism determines which version of a method to call based on the object's actual type at runtime. Abstraction in Java allows hiding implementation details and showing only essential functionality through the use of abstract classes and methods.
This document discusses polymorphism and inheritance concepts in Java. It defines polymorphism as an object taking on many forms, and describes method overloading and overriding. Method overloading allows classes to have multiple methods with the same name but different parameters. Method overriding allows subclasses to provide a specific implementation of a method in the parent class. The document also discusses abstract classes and interfaces for abstraction in Java, and explains access modifiers like public, private, protected, and default.
The document discusses enums in Java. It explains that enums allow a variable to only take on a set list of enumerated values, like days of the week or months. Enums provide type safety and avoid issues with integer-based enums. An enum is a class, and each enum value is an instance of that class. Enums can have fields, methods, and constructors, and provide compile-time type safety compared to integer-based enums.
Polymorphism refers to a function having the same name but being used in different ways and different scenarios, making programming easier and more intuitive. Polymorphism is a fundamental concept in object-oriented programming that allows one function to display multiple functionalities through inheritance, where a child class inherits all methods from the parent class. In Python, polymorphism can be implemented through classes having different methods with the same name, inheritance where child classes can override parent methods, and by defining functions that can accept different object types.
Introduction to method overloading & method overriding in java hdmHarshal Misalkar
This document introduces method overloading and method overriding in Java. Method overloading allows a class to have multiple methods with the same name but different parameters. It increases readability. Method overriding allows a subclass to provide a specific implementation of a method declared in the parent class. It is used for runtime polymorphism where the method being called is determined by the object type. The document provides examples of method overloading by changing number/type of arguments and of method overriding where the subclass overrides the parent's display method.
This chapter discusses control structures in Java programs. It covers relational operators and logical expressions used for comparisons. Selection control structures like if, if-else, and switch statements are examined along with examples. The chapter also provides an example programming problem on cable company billing that demonstrates using control structures and nested conditional logic.
Javascript Prototypal Inheritance - Big PictureManish Jangir
Are you still confused about what the prototypes really are in Javascript. Read the slides from the very begining, you will have a very clear picture about inheritance in Javascript. If you have any questions, please leave a comment. I will try to clarify that thing.
The document discusses polymorphism in object-oriented programming. It defines polymorphism as the ability for objects of different classes related by inheritance to respond differently to the same function call. Polymorphism can be achieved through virtual functions and allows late/dynamic binding at runtime based on the actual object type. The document also discusses early/static binding at compile time, pure virtual functions that define abstract base classes, and concrete derived classes that implement pure virtual functions from the base class.
This document discusses object-oriented programming concepts in Java including objects, classes, constructors, inheritance, polymorphism, and access modifiers.
The key points are:
1) An object represents an entity with a unique identity, state, and behaviors. A class defines common properties and behaviors of objects.
2) Constructors initialize new objects, while methods define object behaviors. Inheritance allows subclasses to inherit properties and behaviors from parent classes.
3) Access modifiers like public, private, and protected control the visibility and accessibility of classes, variables, and methods. Final and abstract modifiers are also used to restrict or require subclassing.
The objectives of the seminar are to shed a light on the premises of FP and give you a basic understanding of the pillars of FP so that you would feel enlightened at the end of the session. When you walk away from the seminar you should feel an inner light about the new way of programming and an urge & motivation to code like you never before did!
Functional programming should not be confused with imperative (or procedural) programming. Neither it is like object oriented programming. It is something different. Not radically so, since the concepts that we will be exploring are familiar programming concepts, just expressed in a different way. The philosophy behind how these concepts are applied to solving problems are also a little different. We shall learn and talk about essentially the fundamental elements of Functional Programming.
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.
Multiple inheritance allows a subclass to inherit from multiple parent classes, combining their functionality. While simple in concept, it can be tricky to implement clearly. The simplest form is a mixin, where a class is designed to be inherited from to share methods and attributes without becoming a unique entity itself. The example demonstrates a MailSender mixin class that a EmailableContact class inherits from along with a Contact class, allowing send_mail functionality to be reused across classes.
