Java program to get information of the current executing thread

Java example to get information of the current executing thread.
Submitted by Nidhi, on April 08, 2022

Problem statement

In this program, we will create a thread with the runnable interface. Then we will create multiple threads and get the thread's information using Thread.currentThread() method.

Source Code

The source code to get information of the currently executing thread is given below. The given program is compiled and executed successfully.

// Java program to get information of the 
// currently executing thread

class MyThread implements Runnable {
  public void run() {
    try {
      System.out.println("Thread : " + Thread.currentThread());
    } 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("First Thread");
    t2.setName("Second Thread");
    t3.setName("Third Thread");

    t1.setPriority(1);
    t2.setPriority(2);
    t3.setPriority(3);

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

Output

Thread : Thread[Second Thread,2,main]
Thread : Thread[First Thread,1,main]
Thread : Thread[Third Thread,3,main]

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 three threads and got thread information using the Thread.currentThread() method in the run() method and printed the result.
