Exception

Example

The following example shows the usage of java.lang.Thread.yield() method.

package com.tutorialspoint;

import java.lang.*;

public class ThreadDemo implements Runnable {

   Thread t;

   ThreadDemo(String str) {

      t = new Thread(this, str);
      // this will call run() function
      t.start();
   }

   public void run() {

      for (int i = 0; i < 5; i++) {
         // yields control to another thread every 5 iterations
         if ((i % 5) == 0) {
            System.out.println(Thread.currentThread().getName() + "
            yielding control...");

            /* causes the currently executing thread object to temporarily 
            pause and allow other threads to execute */
            Thread.yield();
         }
      }

      System.out.println(Thread.currentThread().getName() + " has finished executing.");
   }

   public static void main(String[] args) {
      new ThreadDemo("Thread 1");
      new ThreadDemo("Thread 2");
      new ThreadDemo("Thread 3");
   }
}

Let us compile and run the above program, this will produce the following result −

Thread 1 is yielding control...
Thread 2 is yielding control...
Thread 3 is yielding control...
Thread 1 has finished executing.
Thread 2 has finished executing.
Thread 3 has finished executing.
