Java：创造一个简单的死锁环境

public class Main {

private static final Object oneLock = new Object();
private static final Object twoLock = new Object();

public static void main(String[] args) {
new OneThread().start();
new TwoThread().start();
}

private static class OneThread extends Thread {
@Override
public void run() {
synchronized (oneLock) {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
synchronized (twoLock) {
System.out.println("one");
}
}
}
}

private static class TwoThread extends Thread {
@Override
public void run() {
synchronized (twoLock) {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
synchronized (oneLock) {
System.out.println("two");
}
}
}
}
