java多线程相关

1、实现Runnable接口

class Thread_ implements Runnable{


 public void run() {
  System.out.println("run++++++++++++++++");
   
 }
}
 
//创建对象
Thread_ t=new Thread_();
Thread thread=new Thread(t);
//启动 
thread.start();

2、继承Thread类：

class Thread_ extends Thread{


 public void run() {
  System.out.println("run++++++++++++++++");
   
 }
}


Thread_ t=new Thread_();
t..start();
