============================== Java Interview Questions ============================== Q. How many ways to create a thread in Java ? ANS ---------------- There are two ways to create a thread in Java: 1. Extending the Thread class: - Create a subclass of Thread - Override the run() method - Create an instance of the subclass and start the thread 2. Implementing the Runnable interface: - Create a class that implements Runnable - Implement the run() method - Create a Thread object and pass the Runnable object to it - Start the thread short example of both ways: ============================== Extending Thread: ============================== public class MyThread extends Thread { public void run() { System.out.println("Hello from thread!"); } } MyThread thread = new MyThread(); thread.start(); Implementing Runnable: ============================== public class MyRunnable implements Runnable { public void run() { System.out.println("Hello from thread!"); } } Runnable runnable = new MyRunnable(); Thread thread = new Thread(runnable); thread.start(); React 🔥 if this resource is helpful!
