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();
            }
        }
    }
}

ServletOuptputStream Vs PrintWriter
ServletOutputStream: ServletResponse.getOutputStream() returns a ServletOutputStream suitable for writing binary data in the response. The servlet container does not encode the binary data, it sends the raw data as it is.

PrintWriter: ServletResponse.getWriter() returns PrintWriter object which sends character text to the client. The PrintWriter uses the character encoding returned by getCharacterEncoding(). If the response's character encoding has not been specified then it does default character encoding.
