多线程总结

三种多线程类实现方法

package com.example.multi_thread;

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

public class Overview {
    public static void main(String[] args) {
        new MyThread1().start();
        new Thread(new MyThread2()).start();

        FutureTask<Integer> mythred3 = new FutureTask<Integer>(new MyThread3());
        new Thread(mythred3).start();

    }
}

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

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

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