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

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();
            }
        }
    }
}
