    1.ThrTest.java 继承Thread类方式

    public class ThrTest extends Thread {
        private String name;
         
        public ThrTest() {
             
        }
     
        public ThrTest(String name) {
            this.name = name;
        }
     
        public void run() {
            for (int i = 0; i < 5; i++) {
                System.out.println(name + "运行     " + i);
            }
        }
     
        public static void main(String[] args) {
            ThrTest h1=new ThrTest("A");
            ThrTest h2=new ThrTest("B");
    //        h1.run();
    //        h2.run();
            h1.start();
            h2.start();
        }
    
    }

    2.RunnTest.java实现Runnable接口方式

    public class RunnTest implements Runnable {
        private String name;
        
        public RunnTest() {
             
        }
     
        public RunnTest(String name) {
            this.name = name;
        }
        
        private int ticket = 5;  //5张票
        
        public void run() {
            for (int i=0; i<=20; i++) {
                if (this.ticket > 0) {
                    System.out.println(this.name + Thread.currentThread().getName()+ "正在卖票"+this.ticket--);
                }
            }
        }
    
       
        public static void main(String[] args) {
            RunnTest h1=new RunnTest("线程A");             //资源共享
            
    //        Thread demo= new Thread(h1,"1号窗口");
    //        Thread demo1=new Thread(h1,"2号窗口");
    //        Thread demo2=new Thread(h1,"3号窗口");
            
            Thread demo= new Thread(h1);
            Thread demo1=new Thread(h1);
            Thread demo2=new Thread(h1);
            
            demo.start();
            demo1.start();
            System.out.println("线程启动之前---》" + demo2.isAlive());
            demo2.start();
            System.out.println("线程启动之后---》" + demo2.isAlive());
            
        }
    }
