第一种 继承Thread类

package org.fan.threaddemo;

public class MyThread extends Thread{
    private String name;
    public MyThread(String name){
    	this.name=name;    	
    }
    public void run(){//覆写run()方法
    	for(int i=0;i<30;i++){
    		System.out.println("Thread运行:"+this.name+",i="+i);
    	}
    }
}
//=================
package org.fan.threaddemo;

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();
	}
}
//================
package org.fan.threaddemo;

public class ThreadDemo02 {

	public static void main(String[] args) {
        MyThread mt1=new MyThread("线程A");
        MyThread mt2=new MyThread("线程B");
        mt1.start();
        mt2.start();
	}
}

第二种 实现Runnable接口

package org.fan.runnabledemo;

public class MyThread implements Runnable{
    private String name;
    public MyThread(String name){
    	this.name=name;    	
    }
    public void run(){//覆写run()方法
    	for(int i=0;i<30;i++){
    		System.out.println("Thread运行:"+this.name+",i="+i);
    	}
    }
}
//===================
package org.fan.runnabledemo;

public class RunnableDemo01 {

	public static void main(String[] args) {
        MyThread mt1=new MyThread("线程A");
        MyThread mt2=new MyThread("线程B");
        new Thread(mt1).start();
        new Thread(mt2).start();
	}
}
