class WaitReleaseLockA extends Thread{
private Object lock;
public WaitReleaseLockA(Object lock) {
this.lock=lock;
}
@Override
public void run() {
WaitReleaseLockEx waitReleaseLockEx=new WaitReleaseLockEx();
waitReleaseLockEx.testMethod(lock);
}
}
class WaitReleaseLockB extends Thread{
private Object lock;
public WaitReleaseLockB(Object lock) {
this.lock=lock;
}
@Override
public void run() {
WaitReleaseLockEx waitReleaseLockEx=new WaitReleaseLockEx();
waitReleaseLockEx.testMethod(lock);
}
}
结果：
begin wait!!
begin wait!!
结论：在wait方法执行后，线程会释放锁的 |
