  2. Setting Up Your Development Environment Install JDK Choose IDE Download Oracle or OpenJDK. Set JAVA_HOME variable properly. • IntelliJ IDEA for powerful tools • Eclipse as open-source option • VS Code with Java extensions Configure IDE Customize settings for efficient Java development and debugging.

  3. Java Basics: Syntax and Data Types Core Syntax Data Types Classes, methods, statements form the program structure. Primitives like int, double, boolean; plus String objects. Control Flow If-else statements and loops guide the program logic.

  4. Object-Oriented Programming (OOP) Key Concepts Example • Encapsulation Create a Car class with fields and behaviors using access modifiers. • Inheritance • Polymorphism

  5. Working with Collections List Types Sets and Maps Operations Use ArrayList and LinkedList for ordered collections. HashSet for unique elements, HashMap for key-value pairs. Add, remove, check contents, and iterate collections easily.

  6. Exception Handling Basics Common Exceptions Advanced Use try-catch to handle runtime issues gracefully. Handle IOException, NullPointerException, and others properly. Throw exceptions and use finally for cleanup actions.

  7. Input/Output (I/O) Operations File Access Object Serialization Read and write data to files with streams and Scanner. Save and restore object states efficiently. Practical Use Example: Process data from CSV files programmatically.

  8. Next Steps: Advanced Topics Concurrency Learn multithreading for parallel tasks. Networking Use sockets for communication over networks. Databases Connect to databases with JDBC. GUIsandFrameworks Build interfaces with Swing/JavaFX and explore Spring or Hibernate.
