public class ThreadTest2 {  public static void main(String[] args){    System.out.println("begin our test");    ThreadSleep sleep = new ThreadSleep();    try {      Thread thread1 = new Thread(sleep,"路人甲");      Thread thread2 = new Thread(sleep,"路人乙");      thread1.start();      thread2.start();    }catch(Exception e){      e.printStackTrace();    }    System.out.println("test is over");  }} class ThreadSleep implements Runnable{   int count = 0;   @Override   public void run(){     System.out.println(Thread.currentThread().getName() + " say : hello sleep !!");     count();   }   public void count(){     while(count < 20) {         System.out.println(Thread.currentThread().getName() + " say : count is " + count);         try {           count++;           Thread.sleep(100);         } catch (Exception e) {           e.printStackTrace();         }     }   }}
