多线程问题~~~~~~~~~~
我写2个线程,线程1一直执行,线程2不定时执行,当线程2想执行时,线程1就要停下来让线程2执行。
我像下面这么写行吗? 这不能让这两个线程同时执行,用synchronized没错吧
可我一执行程序就java.lang.IllegalMonitorStateException。指定错误行数是wait()和notify()这两行都错了
谁能指点一下~~~~~谢谢
public class Test{ Object o = new Object(); boolean b = false; public static void main(String[] args) { new Thread(new Thread1()).start(); new Thread(new Thread2()).start(); } private class Thread1 implements Runnable { public void run() { a(); } private void a() throws InterruptedException { synchronized(o) { if(b) { wait(); } //执行内容 } } } private class Thread2 implements Runnable { public void run() { b(); } private void b() throws InterruptedException { b = true; synchronized(o) { //执行内容 b = false; notify(); } } }}
