非常经典的死锁演示代码

package com.wmmad.test;

public class DeadLockMarker {
public static void main(String[] args) throws Exception {
// 资源
final Object lock1 = new Object();
final Object lock2 = new Object();
// 和run2并发执行
Runnable run1 = new Runnable() {
public void run() {
// 锁定lock1资源
synchronized (lock1) {
print("lock1");
sleep();
// 锁定lock2资源
synchronized (lock2) {
print("lock2");
}
}
}
};
// 和run1并发执行
Runnable run2 = new Runnable() {
public void run() {
// 锁定lock2资源
synchronized (lock2) {
print("lcok2");
sleep();
// 锁定lock1资源
