Java is a widely-used, object-oriented programming language that has several fundamental topics essential for beginners. Here are some of the basic topics in Java:

1. Introduction to Java

  • History and Evolution: Understanding the origins and development of Java.
  • Features of Java: Platform independence, object-oriented, simple, secure, etc.
  • Java Environment: JDK (Java Development Kit), JRE (Java Runtime Environment), and JVM (Java Virtual Machine).

2. Basic Syntax

  • Java Program Structure: Understanding the structure of a Java program including the main method.
  • Data Types: Primitive data types (int, char, double, boolean, etc.) and non-primitive data types (arrays, strings, classes).
  • Variables: Declaration, initialization, and scope of variables.
  • Operators: Arithmetic, relational, logical, bitwise, assignment, and other operators.

3. Control Flow Statements

  • Conditional Statements: if, if-else, switch.
  • Looping Statements: for, while, do-while loops.
  • Branching Statements: break, continue, return.

4. Object-Oriented Programming (OOP) Concepts

  • Classes and Objects: Creating classes and objects, understanding the relationship between them.
  • Methods: Defining and invoking methods, method overloading.
  • Constructors: Default and parameterized constructors.
  • Inheritance: Extending classes, the use of super keyword, method overriding.
  • Polymorphism: Compile-time (method overloading) and run-time (method overriding) polymorphism.
  • Encapsulation: Using access modifiers to protect data.
  • Abstraction: Abstract classes and interfaces.

5. Java Libraries and APIs

  • String Handling: String class and its methods, StringBuilder, and StringBuffer.
  • Collections Framework: List, Set, Map, and their implementations like ArrayList, HashSet, HashMap.
  • File I/O: Reading from and writing to files using classes in the java.io package. Visit - Java Course in Pune

6. Exception Handling

  • Types of Exceptions: Checked and unchecked exceptions.
  • Try-Catch Block: Using try, catch, finally blocks.
  • Throw and Throws: Throwing exceptions and declaring them.

7. Multithreading and Concurrency

  • Thread Creation: Extending Thread class or implementing Runnable interface.
  • Thread Lifecycle: New, runnable, blocked, waiting, timed waiting, terminated.
  • Synchronization: Managing access to shared resources.

8. Java Development Tools

  • Integrated Development Environment (IDE): Using IDEs like IntelliJ IDEA, Eclipse, NetBeans for Java development.
  • Build Tools: Maven, Gradle for project management and build automation.

9. Basic GUI Programming

  • Swing and AWT: Basic components and event handling.

10. Basic Networking

  • Networking Basics: Using java.net package for network communication.

These topics form the foundation of Java programming. Mastering them will provide a strong base to explore advanced Java concepts and frameworks.
