Java Thread Yield Examples

  • When a thread executes a thread yield, the executing thread is suspended and the CPU is given to some other runnable thread. This thread will wait until the CPU becomes available again.
  • Technically, in process scheduler's terminology, the executing thread is put back into the ready queue of the processor and waits for its next turn.

Thread Yield Sample Code

Code:
package com.myjava.threads;

import java.util.ArrayList;
import java.util.List;

public class MyThreadYield {
    public static void main(String a[]){
        List<ExmpThread> list = new ArrayList<ExmpThread>();
        for(int i=0;i<3;i++){
            ExmpThread et = new ExmpThread(i+5);
            list.add(et);
            et.start();
        }
        for(ExmpThread et:list){
            try {
                et.join();
            } catch (InterruptedException ex) { }
        }
    }
}

class ExmpThread extends Thread{
    
    private int stopCount;
    public ExmpThread(int count){
        this.stopCount = count;
    }
    public void run(){
        for(int i=0;i<50;i++){
            if(i%stopCount == 0){
                System.out.println("Stoping thread: "+getName());
                yield();
            }
        }
    }
}

Knowledge Centre
What is race condition?
A race condition is a situation in which two or more threads or processes are reading or writing some shared data, and the final result depends on the timing of how the threads are scheduled. Race conditions can lead to unpredictable results and subtle program bugs. A thread can prevent this from happening by locking an object. When an object is locked by one thread and another thread tries to call a synchronized method on the same object, the second thread will block until the object is unlocked.
Famous Quotations
Success consists of going from failure to failure without loss of enthusiasm.
-- Winston Churchill
