简述无卡停车收费系统用到java哪些技术，编程思想大概是怎样？
来一个车java停车缴费系统代码，给一个卡java停车缴费系统代码，计录拿卡时间java停车缴费系统代码，计算剩余车位，还卡时，记录换卡时间，计算剩余车位，价钱通过时间差，用java停车缴费系统代码你们java停车缴费系统代码的单价算，要考虑车型，再加一个判断。
当然，还要识别卡

Q3: Java停车场题，求大神解答
import java.util.ArrayList;
public class Tcat {
//假设停车场有100个停车位
private int carport=100;
//记录空的车位
private int noullcat=100;
//初始化类时传入空余车位数量
public Tcat(int mou) {
noullcat=mou;
}
public void setNoullcat(int noullcat) {
this.noullcat = noullcat;
}
public int getNoullcat() {

}
//记录进来的车的停车时间
private ArrayList lis=new ArrayList();
//车辆进来，空余车位减一
public int catin(){
if(noullcat1){
noullcat--;
lis.add(1);//停车时间
System.out.print("剩余的车位数量:"+noullcat);
return noullcat;//返回剩余的车位数量
}else{
return -1;//返回值-1，表示以及没有空余的车位
}
}
//返回停车费用
public int catvalue(int id){
return (int)lis.get(id)*3;
}
//车辆出去，空余车位加一，返回空余车位,删除车辆停留的列表
public int catto(int id){
if(noullcatcarport){//判断空余车位是否小于最大车位
lis.remove(id);
noullcat++;
}
System.out.println("停车费用:"+catvalue(id));
System.out.println("剩余的车位数量:"+noullcat);
return noullcat;
}
}
