JAVA死锁1

死锁的概念就是：当你去买东西的时候，店小二说给钱给货，你说给货给钱，你们僵住了，就死锁了

public class DeadLock {public static void main(String[] args) {Object o1 = new Object();Object o2 = new Object();Thread t1 = new T1(o1,o2);Thread t2 = new T2(o1,o2);t1.start();t2.start();}}class T1 extends Thread{Object o1;Object o2;T1(Object o1,Object o2){this.o1 = o1;this.o2 = o2;}public void run() {synchronized (o1) {try {Thread.sleep(1000);} catch (InterruptedException e) {e.printStackTrace();}synchronized (o2) {}}}}class T2 extends Thread{Object o1;Object o2;T2(Object o1,Object o2){this.o1 = o1;this.o2 = o2;}public void run() {synchronized (o2) {synchronized (o1) {}}}}
