Java Thread Sleep

  • It makes current executing thread to sleep specified number of milli seconds. Below example shows sample code for thread sleep.

Thread Sleep Sample Code

Code:
package com.myjava.threads;

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

public class MyThreadSuspend {
    public static void main(String a[]){
        List<ExmpThread> list = new ArrayList<ExmpThread>();
        for(int i=0;i<4;i++){
            ExmpThread et = new ExmpThread(i+10);
            list.add(et);
            et.start();
        }
        for(ExmpThread et:list){
            try {
                et.join();
            } catch (InterruptedException ex) { }
        }
    }
}

class ExmpThread extends Thread{
    private int suspendCount;
    public ExmpThread(int count){
        this.suspendCount = count;
    }
    public void run(){
        for(int i=0;i<50;i++){
            if(i%suspendCount == 0){
                try {
                    System.out.println("Thread Sleep: " + getName());
                    Thread.sleep(500);
                } catch (InterruptedException ex) { }
            }
        }
    }
}

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.
