java写的一个死锁例子

public class DeadLock {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
final Object resource1 = "resource1";
final Object resource2 = "resource2";

Thread t1 = new Thread(){
public void run(){
synchronized(resource1){
System.out.println("Thread1:locked resource1");
try{
Thread.sleep(50);
}catch(Exception ex){

}
synchronized(resource2){
System.out.println("Thread1:locked resource2");
}
}
}
};

Thread t2 = new Thread(){
public void run(){
synchronized(resource2){
System.out.println("Thread2:locked resource2");
try{
Thread.sleep(50);
}catch(Exception ex){

}
synchronized(resource1){
System.out.println("Thread2:locked resource1");
}
}
}
};

t1.start();
t2.start();
}
}
