  1. Java Tutorial: From Zero to Hero Learn Java, the backbone of enterprise applications. Gain core skills and best practices. Build real-world projects confidently. by Prabhat Chaudhary

  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 Inheritance Polymorphism Create a Car class with fields and behaviors using access modifiers.

  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 1 2 File Access Object Serialization Read and write data to files with streams and Scanner. Save and restore object states efficiently. 3 Practical Use Example: Process data from CSV files programmatically.

  8. Next Steps: Advanced Topics Concurrency 1 Learn multithreading for parallel tasks. Networking 2 Use sockets for communication over networks. Databases 3 Connect to databases with JDBC. GUIs and Frameworks 4 Build interfaces with Swing/JavaFX and explore Spring or Hibernate.
