我正在写一个客户端数据库。我想根据客户编号了解客户的姓名和家乡。当我输入2号时,我想看到爱丁堡的Arya Stark,当我输入1号时,我想看看伦敦的Jon Snow。为什么我的程序不起作用?如何解决这个问题?
package app;import java.util.Scanner;class Person { String name; String homeCity; int customerNumber;}public class Customers { static Scanner input = new Scanner(System.in); public static void main(String[] args) { String name; System.out.print ("Give a customer card number: "); name = input.next(); Person person1 = new Person(); person1.name = "Jon Snow"; person1.homeCity = "London"; person1.customerNumber = 1; Person person2 = new Person(); person2.name = "Arya Stark"; person2.homeCity = "Edinburgh"; person2.customerNumber = 2; System.out.println(); }}
