java 通过使用wait和notify进行线程之间通信（代码）

public class Test {
    private final Operate operate = new Operate();

    public static void main(String[] args) {    
        new Thread(new Runnable() {
            @Override
            public void run() {
                for (int i = 1; i <= 50; i++) {
                    operate.doSubMethod(i);
                }
            }
        }).start();

        for (int i = 1; i <= 50; i++) {
            operate.doSupMethod(i);
        }
    }
}
class Operate{
    private boolean isSub = true;

    public synchronized void doSubMethod(int i){
        while(!isSub){
            try {
                this.wait();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
        for (int j = 1; j <= 12; j++) {
            System.out.println("Sub--> " + Thread.currentThread().getName() + "\tloop:" + i + "\t第" + j + "次");
        }
        isSub = false;
        notify();
    }

    public synchronized void doSupMethod(int i){
        while(isSub){
            try {
                this.wait();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
        for (int j = 1; j <= 88; j++) {
            System.out.println("Sup--> " + Thread.currentThread().getName() + "\tloop:" + i + "\t第" + j + "次");
        }
        isSub = true;
        notify();
    }
