多线程——线程通信代码

1、多线程——线程通信代码

class PrintNum implements Runnable{
    int num = 1;
    public void run(){
        while (true){
            synchronized (this) {
                notify();
                if (num <= 100){
                    try {
                        Thread.currentThread().sleep(10);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                    System.out.println(Thread.currentThread().getName() + ":" + num);
                    num++;
                }else {
                    break;
                }
                try {
                    wait();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}

public class TestCommunication {
    public static void main(String[] args) {
        PrintNum p = new PrintNum();
        Thread t1 = new Thread(p);
        Thread t2 = new Thread(p);

        t1.setName("甲");
        t2.setName("乙");

        t1.start();
        t2.start();
    }
