线程类的几大创建方法

import java.util.concurrent.Callable;
import java.util.concurrent.FutureTask;

public class Test1 {
    public static void main(String[] args) throws Exception {
        //创建方法1 创建线程类继承Thread类
        MyThread m1=new MyThread();
        m1.start();
        //创建线程方法2；创建线程任务类MyRunable实现Runable接口 将Runable对象交给Thread处理
        MyRunable m2=new MyRunable();
        Thread mm2=new Thread(m2);
        mm2.start();
        //创建Runable匿名内部类对象交给Thread
        Runnable runnable=new Runnable() {
            @Override
            public void run() {
                System.out.println("子线程三号开始跑动");
            }
        };
        new Thread(runnable).start();
        //方法三：利用Callable与FutureTask接口实现
        MyCallable callable=new MyCallable();
        FutureTask futureTask=new FutureTask(callable);
        new Thread(futureTask).start();
        System.out.println(futureTask.get());
    }
}
class MyThread extends Thread{
    @Override
    public void run(){
        System.out.println("子线程一号开始跑动");
    }
}

class MyRunable implements Runnable{
    @Override
    public void run() {
        System.out.println("子线程二号开始跑动");
    }
}
class MyCallable implements Callable{
    @Override
    public Object call() throws Exception {
        return "子线程四号开始跑动";
    }
}
