线程购票小示例

继承Thread

class Cp extends Thread
{
 static int cp=100;
 Cp(String name)
 {
  super(name);
 }
 public void run()
 {
  while(true)
  {
   if(cp>0)
   System.out.println("【"+this.getName()+"】车票编号："+cp--);
  }
 }
}
public class ThreadDemo
{
 public static void main(String[]args)
 {
  Cp c1= new Cp("1号窗口");
  Cp c2= new Cp("2号窗口");
  Cp c3= new Cp("3号窗口");
  Cp c4= new Cp("4号窗口");

  c1.start();
  c2.start();
  c3.start();
  c4.start();
 }
}

实现Runnable

 

class Cp implements Runnable
{
 static int cp=100;
 private String name;
 public Cp(){}
 public Cp(String name)
 {
  this.name=name;
 }
 public void run()
 {
  while(true)
  {
   if(cp>0)
   System.out.println("【"+Thread.currentThread().getName()+"】车票编号："+cp--);
  }
 }
}
public class RunnableDemo
{
 public static void main(String[]args)
 {
  Cp c=new Cp();
  
  

  Thread t1=new Thread(c);
  Thread t2=new Thread(c);
  Thread t3=new Thread(c);
  Thread t4=new Thread(c);

  t1.setName("1号窗口");
  t2.setName("2号窗口");
  t3.setName("3号窗口");
  t4.setName("4号窗口");

  t1.start();
  t2.start();
  t3.start();
  t4.start();
 
 }
}
