写一个ATM取款机的程序~自己写的实在下不下去了!
老师发了一个写好的.jar文件我写了可以说是90%的程序,可是最后实在写不下去了,原因为不知道Map数据的传递问题
现在想请大虾们帮忙写个程序,让我学习一下,谢谢(这里暂时不考虑异常处理)
把这个后缀改成.jar就可以了,运行DOS, java -jar TestBank.jar
TestBank.zip
(9.18 KB)
下面是我写的程序
程序代码：import java.util.*;
public class Test {
public static void main(String[] args) {
Register re = new Register();
Enter en = new Enter();
System.out.println("欢迎使用银行管理系统！");
for (;;) {
System.out.println("1.注册 2.登录 3.退出");
Scanner sc = new Scanner(System.in);
try {
int i = sc.nextInt();
switch (i) {
case 1:
System.out.println("请输入要注册的银行卡种类 1 or 2 >> 1：借记卡 2：信用卡");
i = sc.nextInt();
re.register(i);
continue;
case 2:
en.enter();
continue;
case 3:
System.exit(0);
default:
System.out.println("输入不符合要求！");
}
} catch (Exception e) {
System.out.println("输入不符合要求！");
}
}
}
}
程序代码：import java.util.*;
