三个线程轮流打印ABC十次(wait和notify实现)

先上代码

public class MyThread implements Runnable {

    private String name;

    private String prev;

    private String self;

    public MyThread(String name, String prev, String 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.println(name);
                    self.notify();
                    count--;
                }
                try {
                    prev.wait();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }
    }

    public static void main(String[] args) throws InterruptedException {

        String a = new String("a");
        String b = new String("b&#
