问题
I'm creating a login system that currently uses hard coded integers for a UserID, password and Student number which means they are all numbers. What would I use to be able to make the integers (the UserID and password) words instead of numbers? This is how it currently looks;
public static void main(String[] args) {
final int UserID = 5555;
final int Password = 1234;
final int StudentNumber = 22334455;
回答1:
final int UserID = 5555;
final int Password = 1234;
final int StudentNumber = 22334455;
String UserID_str = String.valueOf(UserID);
String Password_str = String.valueOf(Password);
String StudentNumber_str = String.valueOf(StudentNumber);
回答2:
To convert integers to Strings you can use .toString()
final String UserID = new Integer(5555).toString();
final String Password = new Integer(1234).toString();
final String StudentNumber = new Integer(22334455).toString();
