//回顾总结线程的创建
public class ThreadNew {
    public static void main(String[] args) {
        new MyThread1().start();

        new Thread(new MyThread2()).start();

        FutureTask<Integer> futureTask = new FutureTask(new MyThread3());
        new Thread(futureTask).start();

        try {
            Integer integer = futureTask.get();
            System.out.println(integer);
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (ExecutionException e) {

//1.继承Thread类
class MyThread1 extends Thread{
    @Override
    public void run() {
        System.out.println("MyThread1");
    }
}

//2.实现runnable接口
class MyThread2 implements Runnable{

    @Override
    public void run() {
        System.out.println("MyThread2");
    }
}

//3.实现Callable接口
class MyThread3 implements Callable<Integer>{

    @Override
    public Integer call() throws Exception {
        System.out.println("MyThread3");
        return 100;
    }
}
