public static void main(String[] args){ System.out.println(“欢迎光临腾迅互联会员系统”); System.out.println(“添加用户信息”); System.out.println(“请输入会员号码<4位整数>”); //创建Scanner对象
Scanner sc = new Scanner(System.in);
String num = sc.nextLine(); System.out.println(“请输入会员生日<日/月>”); String birthday = sc.nextLine(); System.out.println(“请输入会员积分”);
String score = sc.nextLine(); if(num.length() == 4){
System.out.println(“会员信息如下”); System.out.println(num + “\t” + birthday + “\t” + score);
}else{
System.out.println(“会员号码输入错误，请输入4位整数！”);
