多线程死锁：package day21.dmo06;
public class Demo {
public static void main(String[] args) {
Object objA = new Object();
Object objB = new Object();
new Thread(()->{
while (true){
synchronized (objA){
synchronized (objB){
System.out.println("小胖同学在走路");
}
}
}
}).start();
new Thread(()->{
while (true){
synchronized (objB){
synchronized (objA){
System.out.println("小小同学再走路");
}
}
}
}).start();
}
}
怎么去查看他是死锁呢？
