java--多线程实现两种方式

1.两种方式继承Thread 和 Runnable接口

    1）Thread类 ：复写run()方法

package org.sh.basic;public class MyThread extends Thread {private String name="";public MyThread(String name){this.name = name;}public void run(){for(int i =0;i<10;i++){System.out.println("Thread 运行"+name+",i="+i);}}}

package org.sh.basic;public class ThreadDemo01 {public static void main(String[] args) {MyThread m1 = new MyThread("thread-A");MyThread m2 = new MyThread("thread-B");m1.start();m2.start();}}

2）实现Runnable接口

package org.sh.basic1;public class MyThread implements Runnable {private String name="";public MyThread(String name){this.name = name;}public void run(){for(int i =0;i<10;i++){System.out.println("Thread 运行"+name+",i="+i);}}}

package org.sh.basic1;public class ThreadDemo01 {public static void main(String[] args) {MyThread m1 = new MyThread("thread-A");MyThread m2 = new MyThread("thread-B");Thread t1 = new Thread(m1);Thread t2 = new Thread(m2);t1.start();t2.start();}}

3）两种方式的区别：

Runnable 相对于Thread的好处：避免单线程局限，一个类只能继承一个类，而可以实现多个接口
