Java program to set a thread name using the setName() method

Java example to set a thread name using the setName() method.
Submitted by Nidhi, on April 08, 2022

Problem Solution:

In this program, we will create a thread with the runnable interface. Then we will create multiple threads and set thread names using the setName() method and get thread names using the getName() method.

Program/Source Code:

The source code to set a thread name using the setName() method is given below. The given program is compiled and executed successfully.

// Java program to set a thread name 
// using setName() method

class MyThread implements Runnable {
  public void run() {
    int i = 0;

    try {
      System.out.println("Thread : " + Thread.currentThread().getId());
    } catch (Exception e) {

    }
  }
}

public class Main {
  public static void main(String[] args) {
    Thread t1 = new Thread(new MyThread());
    Thread t2 = new Thread(new MyThread());
    Thread t3 = new Thread(new MyThread());

    t1.setName("Thread1");
    t2.setName("Thread2");
    t3.setName("Thread3");

    System.out.println("Thread Name: " + t1.getName());
    System.out.println("Thread Name: " + t2.getName());
    System.out.println("Thread Name: " + t3.getName());

    t1.start();
    t2.start();
    t3.start();
  }
}

Output:

Thread Name: Thread1
Thread Name: Thread2
Thread Name: Thread3
Thread : 12
Thread : 11
Thread : 10

Explanation:

In the above program, we created two classes MyThread and Main. We created MyThread class by implementing the Runnable interface.

The Main class contains a main() method. The main() method is the entry point for the program. Here, we created the 3 threads and set their names using the setName() method and get the thread name using the getName() method and printed the result.
