好像是等待一段时间打印一个东西

不好阅读啊！截图或者手打吧

这个是线程的问题了谁都说不准 你运行下试试 啊

断点跟 2000 b=2000

我每次执行结果都一样

public class Deadlock1 implements Runnable
{ int b=100; public synchronized void m1()
throws Exception{ Thread.sleep(5000);
System.out.println("b="+b);}
public synchronized void m2()
throws Exception{ Thread.sleep(2500); b=2000;
System.out.println(b); }
public void run(){ try{m1();}
catch(Exception e){e.printStackTrace(); } }
/** * @param args */
public static void main(String[] args)throws Exception
{ // TODO Auto-generated method stub Deadlock1 t=new Deadlock1(); Thread r=new Thread(t); r.start(); t.m2();
}
}
