简单的线程程序不起作用

Question

嗨，我是一名线程新手java程序员。我一直坚持这个简单的Java程序

public class Multi extends Thread{  
    public void run() { 
        try{ 
            System.out.println("running...");
        }
        catch(Exception e){ 
            System.out.print(e);   
        }
    } 
    public static void main(String[] args){  
        Multi t1=new Multi();  
        t1.run();//fine, but does not start a separate call stack  
    }  
} 

Answer 1

使用start方法启动线程。调用t1.run()方法只是在同一个Thread中同步执行run方法。

t1.start();

阅读：Defining and Starting a Thread

Answer 2

Java 线程由以下方法触发：

t1.start() // This starts a new thread

以下内容：

t1.run();// This calls the run method in the same thread

Answer 3

线程以Thread.Start()

开头

关注线程生命周期

Answer 4

t1.run();// just calls the run method (like any other method) in the same thread.

use t1.start() // starts a new thread.
