启动线程的方法总结

 1 public class A extends Thread{
 2    //重写run方法
 3     public void run(){
 4          add();
 5     }
 6     public void add(){
 7          System.out.println();
 8     }
 9     //开启线程
10     public static void main(String[] args){
11           A a = new A();
12           a.start();
13     }
14 }

 1 public class B implements Runnable{
 2     public void run(){
 3          add();
 4     }
 5     public void add(){
 6          System.out.println("Hello!")
 7     }
 8     public static void main(String [] args){
 9          B b = new B();
10          Thread t = new Thread(b)
11          t.start();
12     }
