Lesson 1: Introduction to Multithreading

1.1 Understanding Multithreading in Java

Multithreading enables concurrent execution of threads within a process to optimize hardware resources. Java supports threads through the Thread class and Runnable interface.

JAVA

// Creating and starting a thread
class MyThread extends Thread {
    public void run() {
        System.out.println("Thread running...");
    }
}

public class Main {
    public static void main(String[] args) {
        MyThread thread = new MyThread();
        thread.start();
    }
}

1.2 Thread Lifecycle and States

A Java thread transitions through NEW, RUNNABLE, RUNNING, BLOCKED, WAITING, and TERMINATED states during its lifecycle.

JAVA

// Checking thread state
Thread.State state = thread.getState();
System.out.println("Thread state: " + state);
