如何在程序中创建出多条线程？

继承Thread类

public class MyThread extends Thread {
   
    @Override
    public void run() {
   
        for (int i = 0; i < 10; i++) {
   
            System.out.println("MyThread运行了" + i);
        }
    }
}

实现Runnable接口

public class MyRunnable implements Runnable {
   
    @Override
    public void run() {
   
        for (int i = 0; i < 10; i++) {
   
            System.out.println("MyRunnable运行了" + i);
        }
    }
}

利用Callable接口、FutureTask类来实现

public class MyCallable implements Callable<String> {
   
    @Override
    public String call() {
   
        return "base.MyCallable 运行了";
    }
}

测试类

public class TestThread {
   
    public static void main(String[] args) throws Exception {
   
        base.MyThread myThread = new base.MyThread();
        myThread.start();

        Runnable myRunnable = new base.MyRunnable();
        new Thread(myRunnable).start();

        Callable<String> myCallable = new MyCallable();
        FutureTask
