Java 介绍避免死锁的几种常见方法

public class DeadLockDemo {

private static String A="A";
private static String B="B";

public static void main(String[] args) {

new DeadLockDemo().deadlock();
}

private void deadlock() {

Thread t1=new Thread(new Runnable() {

@SuppressWarnings("static-access")
@Override
public void run() {

synchronized(A){
try {
Thread.currentThread().sleep(2000);
} catch (InterruptedException e) {

e.printStackTrace();
}
synchronized(B){
System.out.println("1");
}
}
}
});
Thread t2 =new Thread(new Runnable() {

@Override
public void run() {

synchronized(B){
synchronized (A) {
System.out.println("2");
}
}
}
});
t1.start();
t2.start();
}

}
