java多线程--实现Runnable接口方式

因为java类只能继承一个类可以实现多个接口的特性，所以一般情况下不推荐使用继承Thread类实现多线程，下面是实现Runnable接口方式的简单多线程代码

/**
 * 多线程

public class Threads {

    public static void main(String[] args){
        Thread_1 t1=new Thread_1();
        Thread thread1 =new Thread(t1);
        thread1.start();

        Thread_2 t2 =new Thread_2();
        Thread thread2=new Thread(t2);
        thread2.start();

    }
}

class Thread_1 implements Runnable{

    public void run() {
        try {
            //线程暂停一秒
            Thread.sleep(1000); //此方法只是为了更直接的看到线程效果而添加
            System.out.println("执行方法1");
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

    }
}

class Thread_2 implements Runnable{

    public void run() {
        try {
            Thread.sleep(1000);
            System.out.println("执行方法2");
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

    }
}
