java实现停车场管理系统

本文实例为大家分享了java停车场管理系统的具体代码，供大家参考，具体内容如下

//车的类

public class car{
 public String number;//车牌号
 public int inhour;  //进入小时
 public int inminute; //进入分 
 public int insecond; //进入秒
 public int outhour; //开出小时
 public int outminute; //开出分 
 public int outsecond; //开出秒
 public int count; //倒车次数
 public car link;  //队列的指针

//构造方法1
 public car(String num){
 this.number=num;
 this.inhour=0;
 this.inminute=0;
 this.insecond=0;
 this.outhour=0;
 this.outminute=0;
 this.outsecond=0;
 int count=0;
 car link=null;

 }

//构造方法2
 public car(){
 this.number="";
 this.inhour=0;
 this.inminute=0;
 this.insecond=0;
 this.outhour=0;
 this.outminute=0;
 this.outsecond=0;
 int count=0;
 car link=null;
 }
 
 //成员方法：得到指针
 public car getlink(){
 return link;
 }

 //成员方 法：修改指针
 public void setlink(car n){
 link=n;
 }

 //成员方法；得到车牌号
 public String getNum(){
 return number;

}
 
}
