线程的创建

线程创建三个方法：

1.继承thread类

2.实现runnable接口

3.实现callable接口

实例：

//线程的创建方法
public class TestNew {

   public static void main(String[] args) {
       new Mythread1().start();

       Mythread2 mythread2=new Mythread2();
       new Thread(mythread2).start();

       FutureTask<Integer> futureTask=new FutureTask<Integer>(new Mythread3());
       new Thread(futureTask).start();

       try {
           Integer integer=futureTask.get();
           System.out.println(integer);
       } catch (InterruptedException | ExecutionException e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
       }
   }
}

//1.继承thread类
class Mythread1 extends Thread{
   @Override
   public void run() {
       System.out.println("Mythread1");
   }
}

//2.实现runnable接口
class Mythread2 implements Runnable{

   @Override
   public void run() {

       System.out.println("Mythread2");
   }

}

//3.实现callable接口
class Mythread3 implements Callable<Integer>{

   @Override
   public Integer call() throws Exception {

       System.out.println("Mythread3");
       return 100;
   }

}
