Core Java & Multithreading

A hands-on practice repo for Core Java fundamentals, covering OOP, Multithreading, and Java 8 features — structured using standard Java package conventions (com.java8.*) and runnable directly via javac in the terminal (VSCode-friendly, no build tool required).

📁 Project Structure

./
└── com/
    └── java8/
        ├── MyMain.java                          # Entry point — swap imports to run different examples
        ├── classobject/
        │   └── MyClassObject.java               # OOP: encapsulation, constructors, toString
        └── multithreading/
            └── MultithreadingUsingSynchronized.java  # Odd/even printing using synchronized + wait/notify

⚡ How to Run (VSCode Terminal / javac)

From the repo root (wherever you cloned this repo):

# 1. Compile all Java files
javac -d . com/java8/MyMain.java com/java8/classobject/MyClassObject.java com/java8/multithreading/MultithreadingUsingSynchronized.java

# 2. Run the entry point
java com.java8.MyMain

Tip: The -d . flag outputs .class files into the correct package directory structure automatically.
