多线程测试经典错误

今天练习多线程suspend方法想创造一个死锁，但是代码不会出现等待情况，直接就结束了代码如下：

    @Test
    public void test() {
        Thread thread1 = new Thread(() -> {
            synchronized (MyThread.class) {
                String name = Thread.currentThread().getName();
                Thread.currentThread().suspend();
                for (int i = 0; i < 1000; i++) {
                    System.out.println(name + "//" + i);
                }
            }
        }, "Thread1");

        thread1.start();
    }

在Junit环境中创建的多线程都会编程守护线程模式。当test主线程结束后，JVM就会发现系统中已经没有用户进程了，就会结束运行，导致程序不会出现等待情况

给老子加个等待

@Test
    public void test() {
        Thread thread1 = new Thread(() -> {
            synchronized (MyThread.class) {
                String name = Thread.currentThread().getName();
                Thread.currentThread().suspend();
                for (int i = 0; i < 1000; i++) {
                    System.out.println(name + "//" + i);
                }
            }
        }, "Thread1");

        thread1.start();
        try {
            Thread.sleep(999999);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
