Runnable创建线程

public class RunnableDemo implements Runnable{
 @Override
 public void run(){
  int i = 1;
  while(true) {
   System.out.println(Thread.currentThread().getName()+"线程名字"+i);
   i++;
   if(i>30){
    break;
   }
   try{
    Thread.currentThread().sleep(3000);
  }catch(InterruptedException e){
    e.printStackTrace();
  }
 }
}
public static void main(String[] args){
 Thread zhangshan = new Thread(new RunnableDemo());
  zhangshan.setName("zhangshan");
  zhangshan.start();
}

Thread创建线程

public class ThreadDemo extends  Thread{
 @Override
 public void run(){
   super.run();
   int i=1;
   while(true){
    System.out.println(this.getName()+"线程名"+i);
    i++;
     if(i>30){
      break;
     }
     try{
       this.sleep(3000);
     }catch(InterruptedException e){
       e.printStackTrace();
     }
   }
 }
  public static void main(String[] args){
    ThreadDemo zhangshan = new ThreadDemo();
     zhangshan.setName("zhangshan");
     zhangshan.start();
  }
}
