Handler Runnable和Thread之间的区别和联系 应用

java两种式实现线程种继承Thread类种实现Runnable接口；Thread类java.lang包定义类要继承Thread类同覆写本类run()实现线程操作类能继承父类局限
面看例：

package org.thread.demo;
class MyThread extends Thread{
private String name;
public MyThread(String name) {
super();
this.name = name;
}
public void run(){
for(int i=0;i<10;i++){
System.out.println("线程始："+this.name+",i="+i);
}
}
}
package org.thread.demo;
public class ThreadDemo01 {
public static void main(String[] args) {
MyThread mt1=new MyThread("线程a");
MyThread mt2=new MyThread("线程b");
mt1.run();
mt2.run();
}
}
