多线程28-总结

线程总结

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

//回顾总结线程的创建
public class ThreadNew {
    public static void main(String[] args) {
        MyThread1 myThread1=new MyThread1();
        myThread1.start();//new MyThread1().start()

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

        FutureTask<Integer> futureTask = new FutureTask<Integer>(new MyThread3());
        new Thread(futureTask).start();
        try {
            Integer integer = futureTask.get();
            System.out.println(integer);
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (ExecutionException e) {
            e.printStackTrace();
        }


    }
}

//1.继承Tread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(){
        System.out.println("mythread3");
        return 100;
    }
}

输出：
mythread1
mythread2
mythread3
100
