ThreadDeath 理解
1 public class RunnableTest2 { 2 public static Object obj1 = new Object(); 3 public static Object obj2 = new Object(); 4 private MyThread1 t1 = new MyThread1(); 5 private MyThread2 t2 = new MyThread2(); 6 public static void main(String[] args) { 7 RunnableTest2 tr = new RunnableTest2(); 8 tr.t1.start(); 9 tr.t2.start(); 10 } 11 } 12 13 class MyThread1 extends Thread { 14 @Override 15 public void run() { 16 System.out.println(Thread.currentThread()+"锁定了obj1,过2秒锁定obj2去"); 17 synchronized (RunnableTest2.obj1) { 18 try { 19 Thread.sleep(2000); 20 synchronized (RunnableTest2.obj2) { 21 System.out.println("1"); 22 } 23 } catch (InterruptedException e) { 24 e.printStackTrace(); 25 } 26 } 27 } 28 } 29 30 class MyThread2 extends Thread { 31 @Override 32 public void run() { 33 System.out.println(Thread.currentThread()+"锁定了obj2,过2秒锁定obj1去"); 34 synchronized (RunnableTest2.obj2) { 35 36 try { 37 Thread.sleep(2000); 38 synchronized (RunnableTest2.obj1) { 39 System.out.println("2"); 40 } 41 } catch (InterruptedException e) { 42 // TODO Auto-generated catch block 43 e.printStackTrace(); 44 } 45 46 47 } 48 } 49 }
打印结果:
Thread[Thread-0,5,main]锁定了obj1,过2秒锁定obj2去
Thread[Thread-1,5,main]锁定了obj2,过2秒锁定obj1去
