死锁的情况
千万不要在使用中造成这种情况
[cpp] view plain copy print ? package day13; class Test implements Runnable { private boolean flag; Test(boolean flag) { this.flag = flag; } public void run() { if(flag) { while(true) synchronized(MyLock.locka) { System.out.println(Thread.currentThread().getName()+"..if locka...."); synchronized(MyLock.lockb) { System.out.println(Thread.currentThread().getName()+"..if lockb...."); } } } else { while(true) synchronized(MyLock.lockb) { System.out.println(Thread.currentThread().getName()+"..else lockb...."); synchronized(MyLock.locka) { System.out.println(Thread.currentThread().getName()+"..else locka...."); } } } } } class MyLock { public static final Object locka = new Object(); public static final Object lockb = new Object(); } public class DeadLockTest { public static void main(String[] args) { Test a = new Test(true); Test b = new Test(false); Thread t1 = new Thread(a); Thread t2 = new Thread(b); t1.start(); t2.start(); } }
