java實現停車場管理系統
阿新 • • 發佈：2020-01-07
本文例項為大家分享了java停車場管理系統的具體程式碼，供大家參考，具體內容如下
//車的類
public class car{
public String number;//車牌號
public int inhour; //進入小時
public int inminute; //進入分
public int insecond; //進入秒
public int outhour; //開出小時
public int outminute; //開出分
public int outsecond; //開出秒
public int count; //倒車次數
public car link; //佇列的指標
//構造方法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;
}
//構造方法2
public car(){

this.inminute=0;
this.insecond=0;
this.outhour=0;
this.outminute=0;
this.outsecond=0;
int count=0;

}
//成員方法：得到指標
public car getLink(){
return link;
}
//成員方 法：修改指標
public void setLink(car n){

}
//成員方法；得到車牌號
public String getNum(){
