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

package text;

/**
 * 多线程
 * @author admin
 *
 */
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);
            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();
        }

    }
}
    

循环

package test.bean;

public class xc {

     public static  void main(String[] args){
         for(int i = 0 ; i < 10 ; i ++ ){
             test t = new test();
             new Thread(t).start();
         }
     }
}
class test implements Runnable{
    public void run() {
        System.out.println("线程："+Thread.currentThread().getName() + "执行");
    }
}
