你这个不用数据库真的是有点难搞
我写了个用集合存储的,你看看,能否帮上你
java.util.ListString list = new ArrayListString();
list.add("qq=123");//存储的时候用(用户名=密码)的形式
list.add("ww=456");
String username = "qq";
String password = "123";
for (int i = 0; i list.size(); i++) {
String num = username +"="+password;
if(num.equals(list.get(i))){
System.out.println("登录成功");
break;
}
}
