Question

Thread thread1;
thread1 = new Thread() {
    public void run() {
        try {
            Thread.sleep(1700);
        } catch (InterruptedException ex) {
            Logger.getLogger(TestThread.class.getName()).log(Level.SEVERE, null, ex);
        }
       System.out.println("testing");
    }
};
Thread thread2;
thread2 = new Thread() {
    public void run() {
        try {
            // ... your code here
            Thread.sleep(1000);
            System.out.println("testing");
        } catch (InterruptedException ex) {
            Logger.getLogger(TestThread.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
};
thread1.start();
thread2.start();
System.out.println("testing");

这是我的程序的条纹版本，并突出显示我需要在它睡觉时传递的问题，但在环顾四周后我似乎无法通过它我只能找到有关传递给runnable的信息。

尝试在课程下面运行，你有任何问题吗

public class TestThread {

    volatile static int time = 1700;

    public static void main(String[] args) {


        Thread thread1 = new Thread() {
            @Override
            public void run() {
                try {
                    Thread.sleep(time);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                System.out.println("Thread1 Sleeped for : " + time + " millis");
            }
        };
        thread1.start();

        Thread thread2 = new Thread() {
            @Override
            public void run() {
                try {
                    Thread.sleep(time);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                System.out.println("Thread2 Sleeped for : " + time + " millis");
            }
        };
        thread2.start();
    }

}

您可以尝试创建一个占用休眠时间和自定义代码的线程工厂：

interface CodeExecutor {
    void execute();
}

static class ThreadFactory {
    public static Thread newThread(int sleepTime, CodeExecutor customCode) {
        return new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    customCode.execute();
                    Thread.sleep(sleepTime);
                    System.out.println("testing");
                } catch (InterruptedException ex) {
            Logger.getLogger(TestThread.class.getName()).log(Level.SEVERE, null, ex);
                }
            }
        });
    }
}

public static void main(String[] args) {
    Thread thread1 = ThreadFactory.newThread(100, new CodeExecutor() {
        @Override
        public void execute() {
            // here goes your custom code
        }
    });

    thread1.start();
    // create other threads
}

我需要将一个变量传递给一个线程
