从项目中删除静态信息

Question

他们是一种简单的方法来在这些方法之间传递变量和数组，而不需要超长的方法签名？目前我正在使用这些静态技术，但我知道这不是“正确”的做法，但如果我在签名中通过它们，它会使一切看起来很难看。那么传递像lastName，firstName和role这样的变量的“正确”方式是什么？

// Program wide variables 
//static String firstName; // First name from the file 
static String lastName; // Last name from the file 
static String username; // Username 
static String password; 
static String role; 
static String email; 
static String answersFile; // Answers file in use with path and ext 
static String[] answeredQ = new String[questAsks]; // Recording the question asked 
static Boolean[] answeredA = new Boolean[questAsks]; //Recording users answer 
static Boolean[] answeredC = new Boolean[questAsks]; //Recording the correct answer 

public static void main(String Args[]) throws FileNotFoundException, IOException { 
    // Main method that contains major control functions; a quick summary of the program; fucking magic 
} 

public static void quiz(String testType) throws HeadlessException, IOException { 
    String testBankFile = path + testType + ".txt"; 
    Random rand = new Random(); 
    int questionCount = 0, right = 0, wrong = 0; 
    long startTime = System.currentTimeMillis(); // Setting the start time in milliseconds 
    while (questionCount < questAsks) { // Loop that will ask all the questions 
     int r = rand.nextInt(getLines(testBankFile)); 
     boolean ans = promptQuestion(read(r, testBankFile), questionCount + 1); // For some reason this makes it work 
     answeredQ[questionCount] = read(r, testBankFile); 
     answeredA[questionCount] = ans; 
     answeredC[questionCount] = parseA(read(r, answersFile)); 

     if (ans != parseA(read(r, answersFile))) { 
      wrong++; 
     } else if (ans == parseA(read(r, answersFile))) { 
      right++; 
     } 
     questionCount++; 
    } 
    JOptionPane.showMessageDialog(null, "You got " + wrong + " wrong and " + right + " correct."); 
    long endDiff = (System.currentTimeMillis() - startTime); 
    makeReport(firstName, lastName, username, printTime(endDiff), testType, right); 
} 
// Generates a report report(first, last, score, time, array of answers) 
public static void makeReport(String first, String last, String user, String time, String testType, int score) throws IOException { 
    DateFormat dateF = new SimpleDateFormat(dateFormat); 
    Date date = new Date(); 
    String fileName = user + "_COSC236_Quiz_" + dateF.format(date) + ".txt"; 
    File file = new File(fileName); 
    file.createNewFile(); 

    FileWriter out = new FileWriter(fileName); 

    double percent = (((double) score)/((double) questAsks) * 100); 
    out.write("Name: " + first + " " + last + "\n"); 
    out.write("Score: " + percent + "%\n"); 
    out.write("Elapsed time: " + time + "\n"); 
    out.write("Test type: " + testType + "\n"); 
    out.write("---------------------------------------------------------------------\n"); 
    out.write(" Users\tCorrect\tQuestion\n"); 
    for (int i = 0; i < answeredQ.length; i++) { 
     out.write(i + 1 + ".) "); 
     out.write(answeredA[i].toString() + "\t"); 
     out.write(answeredC[i].toString() + "\t"); 
     out.write(answeredQ[i] + "\n"); 
    } 
    out.close(); 
} 

// Boolean login method | login(tries allowed, source file) 
public static void login(int tries, String source) throws FileNotFoundException, IOException { 

    String[] loginInfo; 
    boolean invalid = false; 
    for (int x = 0; x < tries; x++) { 
     invalid = false; 
     loginInfo = promptLogin(); 
     if (loginInfo[0].toLowerCase().equals("done")) { 
      System.exit(0); 
     } 
     for (int i = 0; i < getLines(source); i++) { 
      StringTokenizer st = null; 
      st = new StringTokenizer(read(i, source)); 
      String user = st.nextToken(); 
      String pass = st.nextToken(); 
      if (user.equals(loginInfo[0])) { 
       if (pass.equals(loginInfo[1])) { 
        username = loginInfo[0]; 
        password = loginInfo[1]; 
        firstName = st.nextToken(); 
        lastName = st.nextToken(); 
        email = st.nextToken(); 
        role = st.nextToken(); 
        if (role.toLowerCase().equals("instructor")) { 
         promptInstructor(); 
         JOptionPane.showMessageDialog(null, exitedInstructorMode); 
         break; 
        } else { 
         run(); 
        } 
       } else { 
        invalid = true; 
       } 
      } else { 
       invalid = true; 
      } 
     } 
     if(invalid) { 
      JOptionPane.showMessageDialog(null, invalidLogin); 
     } 
    } 
    JOptionPane.showMessageDialog(null, tooManyAttempts); 
} 

}

Answer 1

为什么不只是使持有，你需要绕过

Answer 2

使用OOP的值的类。创建CLSS你反对

例如：

class User{ 
    String lastName; 
    String username; 
    String password; 
    String role; 
    String email; 
... 

    public static User login(int tries, String source) throws FileNotFoundException, IOException { 
    //this you read User param and add new User 
    return user; 
    } 

} 

而现在，你需要姓氏，用户名，密码，角色或电子邮件，可以 通用户实例
