將完整單詞用作登錄系統的變量

Question

我正在創建一個登錄系統，該系統當前使用硬編碼整數作爲UserID，密碼和學號，這意味着它們都是數字。我會用什麼來使整數（用戶名和密碼）字而不是數字？這是它目前的樣子;

public static void main(String[] args) { 

    final int UserID = 5555; 
    final int Password = 1234; 
    final int StudentNumber = 22334455; 

Answer 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); 

Answer 2

要轉換整數轉換爲字符串，您可以使用.toString()

final String UserID = new Integer(5555).toString(); 
final String Password = new Integer(1234).toString(); 
final String StudentNumber = new Integer(22334455).toString();
