8月7日 Java多线程

基础代码：

package com.pyc.test;

public class MainTest {

   public static void main(String[] args) {
       // TODO Auto-generated method
       Thread th = new OneThread();
       Thread th1 = new TwoThread();//分出的线程从分出就与主线程无关了
th.start();
th1.start();
System.out.println("main方法结束");
   }

}
class OneThread extends Thread{
   @Override
   public void run() {
       // TODO Auto-generated method stub
//       super.run();
       for(int i = 0;i<100;i++) {
           System.out.println("这是第一个线程"+i);
       }
   }
}
class TwoThread extends Thread{
   public void run() {
       // TODO Auto-generated method stub
//       super.run();
       for(int i = 0;i<100;i++) {
           System.out.println("这是第二个线程"+i);
       }
   }
}

第二块代码：

MainTest.java

package com.pyc.test;

public class MainTest {

   public static void main(String[] args) {
       // TODO Auto-generated method
       Thread th = new OneThread();
       Thread th1 = new Thread(new TwoThread());//分出的线程从分出就与主线程无关了
       new Thread(new Runnable() {

           @Override
           public void run() {
               // TODO Auto-generated method stub

           }
       }).start();
th.start();
th1.start();
System.out.println("main方法结束");
   }

}
class OneThread extends Thread{
   @Override
   public void run() {
       // TODO Auto-generated method stub
//       super.run();
       for(int i = 0;i<100;i++) {
           try {
               Thread.sleep(5000);
           } catch (InterruptedException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
           }
           System.out.println("这是第一个线程"+i);
       }
   }
}
class TwoThread extends Thread{
   public void run() {
       // TODO Auto-generated method stub
//       super.run();
       for(int i = 0;i<100;i++) {
           System.out.println("这是第二个线程"+i);
       }
   }
}

TestSleep.java

package com.pyc.test;

public class TestSleep implements Runnable {

   SetType set = new SetType();
   public static void main(String[] args) {
       // TODO Auto-generated method stub
       TestSleep test = new TestSleep();
       Thread th = new Thread(test);
       Thread th1 = new Thread(test);
       th.setName("t1");
       th1.setName("t");
   }
   @Override
   public void run() {
       // TODO Auto-generated method stub
       set.add(Thread.currentThread().getName());
   }

}
class SetType{
   public static int num = 0;
   public void add(String name) {
       num++;
       try {
           Thread.sleep(1000);
       } catch (InterruptedException e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
       }//暂停一秒
       System.out.println(name+"线程调用第"+num+"个线程");
   }
}
