Java program to get the state of the currently executing thread

Java example to get the state of the currently executing thread.
Submitted by Nidhi, on April 09, 2022

Problem statement

In this program, we will create a thread with the runnable interface. Then we will create multiple threads and get state of current thread using Thread.currentThread().getState() method.

Source Code

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

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

class MyThread implements Runnable {
  public void run() {
    try {
      Thread.State thrdState = Thread.currentThread().getState();
      System.out.println("Thread State: " + thrdState);
    } 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.start();
    t2.start();
    t3.start();
  }
}

Output

Thread State: RUNNABLE
Thread State: RUNNABLE
Thread State: RUNNABLE

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 get the current state of the thread using the Thread.currentThread().getState() method in the run() method and printed the result.
