Hello friends,
In this presentation, I explain topic such as:
1. inheritance
2. type of inheritance
3. overriding
4. super keyword
5. abstract method
6. abstract classes
7. constructor in the derived class
This is slide presentation that describes inner classes in java and illustrates the concept using demo examples with code shared on both GitHub and dev community.
This document provides an overview of object-oriented programming (OOP) concepts in C#, including classes, objects, the class lifecycle, accessibility, static vs instance, inheritance, polymorphism, and encapsulation. It also addresses some common questions about overriding methods, overriding private methods, declaring override methods as static, and whether a class can be instantiated if its constructor is private. The document was presented by Eng. Medhat Dawoud and encourages contacting him with any other questions.
The document summarizes the main components and block structure of a computer system. It outlines the input unit which reads data and programs into the computer. It describes the primary and secondary memory units for temporary and permanent storage. The arithmetic logic unit performs arithmetic and logical operations on data as instructed. The control unit manages the movement of data and instructions between memory and the central processing unit which executes stored programs. The output unit delivers results to the user and allows machine to human communication.
This document discusses parameter passing mechanisms in programming languages. It explains different parameter passing techniques like call by value, call by reference, call by name. It also discusses formal and actual parameters, how they are associated during a subprogram call, and how their values are copied or linked during the subprogram entry and exit. Implementation of formal parameters involves storage in the activation record and handling input/output types by copying or using pointers.
The document discusses concepts related to sequence control and subprograms in programming languages. It covers conditional statements, loops, exception handling, subprogram definition and activation, and subprogram environments. Key points include implicit and explicit sequence control using statements, precedence and associativity rules for expressions, stack-based implementation of subprogram calls, and static versus dynamic scoping of identifiers through referencing environments.

The document discusses various Java concepts including object-oriented principles, inheritance, polymorphism, encapsulation, constructors, methods, exceptions, threads, and memory management. It provides definitions and explanations of key terms like inheritance, polymorphism, method overloading, overriding, checked and unchecked exceptions, static and non-static methods, and the differences between concepts like ArrayList and Vector, and method overloading versus overriding.
This document provides an overview of Java fundamentals including classes, objects, encapsulation, abstraction, inheritance, polymorphism and other core OOP concepts. Key points covered include:
- Classes contain variable declarations and method definitions while objects have state, behavior and identity.
- Encapsulation is achieved by declaring class variables as private and providing public get and set methods.
- Abstraction hides certain details and shows only essential information to the user using abstract classes and interfaces.
- Inheritance allows classes to extend functionality from other classes in a hierarchical manner to achieve code reuse.
- Polymorphism allows a single action to be performed in different ways depending on the object used.
Here are the key principles of Object-Oriented Programming (OOP) in Java:
1. Encapsulation: It wraps code and data together into a single unit called class. The data in a class can be accessed and manipulated only through the methods of the class. This prevents data from direct modification which is called data hiding.
2. Inheritance: It allows one class to acquire properties of another class. The child class inherits attributes and behaviors of the parent class. This allows code reusability and is-a relationship between classes.
3. Polymorphism: It allows different classes to have same method name but with different implementations. This is achieved by method overriding in Java. Polymorphism allows one
This document discusses nested classes in Java. It defines nested classes as classes defined within other classes. There are two main types - non-static nested classes and static nested classes. Non-static nested classes can access private members of the outer class and require an outer class instance, while static nested classes behave like regular classes and do not require an outer class instance. The document covers the different types of non-static nested classes and provides examples to illustrate their usage and properties. It also compares static and non-static nested classes and discusses the advantages and disadvantages of using nested classes.

Java is a computer programming language developed by James Gosling at Sun Microsystems. Java was first released in 1995 and has since become one of the most popular programming languages with an estimated 12 million developers using it.
The document discusses reflection in Java, including:
- What reflection is and its history of use in Java versions
- How reflection allows programs to observe and manipulate objects at runtime without knowing their type at compile time
- Common uses of reflection like loading classes, getting methods/fields, and invoking methods
- Myths about reflection not being useful or reducing performance
- Advanced reflection topics like using it with design patterns
- Improvements to reflection in later Java versions
Reflection allows programs to be more flexible, extensible, and pluggable by observing and manipulating objects at runtime.
Java is an object-oriented programming language initially developed by Sun Microsystems. It is platform independent because the Java code is compiled into bytecode, which can run on any Java Virtual Machine (JVM). Java is considered more secure than other languages because it does not use pointers, handles memory allocation automatically through garbage collection, and catches errors at compile-time. The key differences between C and Java are that Java does not support pointers, global variables, or preprocessor directives and it has automatic memory management and strict object-oriented approach.
This document provides an overview of the Java programming language. It discusses the history and origins of Java, defines what Java is, and lists some of its common uses. It then provides reasons for using Java, including that it works on multiple platforms, is one of the most popular languages, is easy to learn, is open-source, and has a large community. The document also introduces key Java concepts like syntax, variables, data types, classes and objects, inheritance, and packages.
Java is a high-level programming language originally developed by Sun Microsystems and released in 1995. It runs on a variety of platforms such as Windows, Mac OS, and various versions of UNIX. Key features of Java include being object-oriented, platform independent, robust, interpreted, and multi-threaded. When Java is compiled, it is compiled into platform independent byte code that is distributed and interpreted by the Java Virtual Machine (JVM) on whichever platform it is being run on, providing platform independence. Common Java IDEs include Netbeans and Eclipse.
This document discusses the core concepts of object-oriented programming (OOP) in Java, including inheritance, encapsulation, abstraction, and polymorphism. It provides examples of each concept: inheritance allows classes to inherit properties from parent classes; encapsulation involves hiding data and code together within classes; abstraction deals with hiding details and focusing on essentials through abstract classes and interfaces; polymorphism allows classes to take different forms. The document uses examples like vehicles and medical capsules to illustrate how each OOP concept works in Java code.
Inheritance in java introduces the concept of reusability by implementing a mechanism in which one object acquires all the properties and behaviors of the parent object.
Inheritance in Java is a mechanism in which one object acquires all the properties and behaviors of a parent object. It is an important part of OOPs (Object Oriented programming system).
The idea behind inheritance in Java is that you can create new classes that are built upon existing classes. When you inherit from an existing class, you can reuse methods and fields of the parent class. Moreover, you can add new methods and fields in your current class also.
Inheritance represents the IS-A relationship which is also known as a parent-child relationship.
The document discusses key concepts in class definitions in VB.Net including class structure with attributes, access modifiers, and inheritance indicators. It also covers class members like functions and encapsulation. Constructors and destructors are described as special member functions. Inheritance allows one class to inherit properties from another base class.

Consistent toolbox talks are critical for maintaining workplace safety, as they provide regular opportunities to address specific hazards and reinforce safe practices.
These brief, focused sessions ensure that safety is a continual conversation rather than a one-time event, which helps keep safety protocols fresh in employees' minds. Studies have shown that shorter, more frequent training sessions are more effective for retention and behavior change compared to longer, infrequent sessions.
Engaging workers regularly, toolbox talks promote a culture of safety, empower employees to voice concerns, and ultimately reduce the likelihood of accidents and injuries on site.
The traditional method of conducting safety talks with paper documents and lengthy meetings is not only time-consuming but also less effective. Manual tracking of attendance and compliance is prone to errors and inconsistencies, leading to gaps in safety communication and potential non-compliance with OSHA regulations. Switching to a digital solution like Safelyio offers significant advantages.
Safelyio automates the delivery and documentation of safety talks, ensuring consistency and accessibility. The microlearning approach breaks down complex safety protocols into manageable, bite-sized pieces, making it easier for employees to absorb and retain information.
This method minimizes disruptions to work schedules, eliminates the hassle of paperwork, and ensures that all safety communications are tracked and recorded accurately. Ultimately, using a digital platform like Safelyio enhances engagement, compliance, and overall safety performance on site. https://safelyio.com/

Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.

A block is the structure that defines the
container of a method, class, or function.
In JAVA there blocks are defined by a
signature and the brackets that surround the
language.
3. EExxaammppllee
Class calls: are used to bring external class
parameters to the program that you are writing.
#import <Foundation/Foundation.h>
#import "NSData+base64.h"
4. EExxaammppllee ccoonntt..
Class Declaration: Classes are declared with
a simple structure.
The first part is the class signature
class MyClass {
// variable declaration
// method signature
}
5. EExxaammppllee ccoonntt..
The second part of the class is the Curly
braces that surround the class itself.
These define the code that the class uses.
class MyClass {
// variable declaration
// method signature
}
