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) { }
            }
        }
    }
}

Stream and types of Streams
A Stream is an abstraction that either produces or consumes information. There are two types of Streams and they are:

Byte Streams: Provide a convenient means for handling input and output of bytes. Byte Streams classes are defined by using two abstract classes, namely InputStream and OutputStream.

Character Streams: Provide a convenient means for handling input & output of characters. Character Streams classes are defined by using two abstract classes, namely Reader and Writer.
Famous Quotations
There is a great difference between worry and concern. A worried person sees a problem, and a concerned person solves a problem.
