Java thread Programming - Create a Basic Thread to Print "Hello, World!"

Last update on December 21 2024 10:03:17 (UTC/GMT +8 hours)

Write a Java program to create a basic Java thread that prints "Hello, World!" when executed.

Sample Solution:

Java Code:

public class Hello_world_thread extends Thread {
  @Override
  public void run() {
    System.out.println("Hello, World!");
  }
  public static void main(String[] args) {
    Hello_world_thread thread = new Hello_world_thread();
    thread.start();
  }
}

Sample Output:

Hello, World!

Explanation:

In the above exercise,

In the main method, an instance of the Hello_world_thread class is created, and the start() method is called on that instance. This starts the thread's execution, which invokes the over ridden run() method.

When the program is executed, it creates another thread and runs it, causing "Hello, World!" to be printed to the console.
