用Java实现一个必定会产生死锁的程序

public class TestLock { public static void main(String[] args) { Thread t1 = new Thread(new deadLock(false)); Thread t2 = new Thread(new deadLock(true)); t1.start(); t2.start(); } } class deadLock implements Runnable{ boolean flage; deadLock(boolean flage){ this.flage=flage; } Object obj1=new Object(); Object obj2=new Object(); public void run() { if(this.flage){ synchronized (obj1) { System.out.println(Thread.currentThread().getName()+"hava o1"); try{ Thread.sleep(100); }catch(Exception e){ e.printStackTrace(); } synchronized (obj2) { System.out.println(Thread.currentThread().getName()+"hava o2"); } } }else{ synchronized (obj2) { System.out.println(Thread.currentThread().getName()+"hava o2"); try{ Thread.sleep(100); }catch(Exception e){ e.printStackTrace(); } synchronized (obj1) { System.out.println(Thread.currentThread().getName()+"hava o1"); } } } } }
