Introduction to Java

Java is a high-level, object-oriented programming language developed by Sun Microsystems in 1995. It is designed to have "write once, run anywhere" (WORA) capability, meaning that compiled Java code can run on any device with a Java Virtual Machine (JVM).

Java is widely used in various industries due to its portability, scalability, and robustness. It is the backbone of many enterprise-level applications and Android mobile applications.

Setting Up Java Development Environment

Before you start coding in Java, you need to set up a Java Development Kit (JDK) and an Integrated Development Environment (IDE) like IntelliJ IDEA or Eclipse.

Java Syntax and Structure

Java uses a combination of keywords, identifiers, literals, and operators to create code. Understanding the basic syntax and structure is crucial for writing effective Java programs.

Variables and Data Types

In Java, variables are used to store data. Each variable has a data type that determines the kind of data it can hold. Learn about the different data types and how to declare and use variables in Java.

Control Structures

Control structures in Java allow you to control the flow of execution of your program. Learn about if-else statements, loops (for, while, do-while), and switch statements.

Classes and Objects

Java is an object-oriented programming language, which means everything in Java is an object. In this section, we'll explore how to create classes and objects in Java.

Inheritance and Polymorphism

Inheritance allows you to create a new class (derived class) from an existing class (base class). Polymorphism allows objects of different classes to be treated as objects of a common superclass. Learn how to use inheritance and polymorphism in Java.

Exception Handling

Exception handling is an essential part of Java programming. Learn how to catch, handle, and throw exceptions in your Java applications.

Collections and Generics

Java provides a rich collection framework that allows you to store and manipulate groups of objects. Learn about the different collection classes like ArrayList, LinkedList, HashMap, and how to use generics to ensure type safety.

Advanced Topics

In this section, we'll explore some advanced topics in Java programming, including multithreading, file handling, networking, and database connectivity.
