线程同步示例

标签：err   row   zed   题意   new   public   --   str   throw   

题意：建立三个线程，A线程打印10次A，B线程打印10次B,C线程打印10次C，要求线程同时运行，交替打印10次ABC。这个问题用Object的wait()，notify()就可以很方便的解决。

代码如下：

public class MyThreadPrinter2 implements Runnable {

private String name;
private Object prev;
private Object self;

private MyThreadPrinter2(String name, Object prev, Object self) {
this.name = name;
this.prev = prev;
this.self = self;
}

@Override
public void run() {
int count = 10;
while (count > 0) {
synchronized (prev) {
synchronized (self) {
System.out.print(name);
count--;

self.notify();
}
try {
prev.wait();
} catch (InterruptedException e) {
e.printStackTrace();
}
}

}
}

public static void main(String[] args) throws Exception {
Object a = new Object();
Object b = new Object(http://www.amjmh.com/v/);
Object c = new Object();
MyThreadPrinter2 pa = new MyThreadPrinter2("A", c, a);
MyThreadPrinter2 pb = new MyThreadPrinter2("B", a, b);
MyThreadPrinter2 pc = new MyThreadPrinter2("C", b, c);


new Thread(pa).start();
new Thread(pb).start();
new Thread(pc).start(); }
}
