Question

Java: Please help with my Tester. I'm having a hard time figuring out my error. Thank you.

What the tester requires:

The AccountTester

1. This class should consists of a main method that tests all the methods in each class, either directly by calling the method from the Tester or indirectly by having another method call a method.
2. User and Bot information will be read from a file. A sample file is provided. Use this file format to aid in grading. Using file processing makes entering and testing program with data sets much more efficient.
3. The file created should include valid and invalid passwords that fully tests the application.
4. Included is file called data.txt contains Account data. Your project will be graded using a similar input file. Your project must run with an input file formatted as data.txt is formatted. Note the file format is as follows:
   1. Character designation of type of player ( u- User, b - Bot)
   2. User – username,fullname,deptCode
   3. Bot – botFilename,category,dateUpdated,createdBy
   4. Account data – common data for both types
5. Creates an array of Account objects.
   1. Populate the array with both User and Bot objects.
   2. Retrieves each object stored in the array and calls its toString method polymorphically and displays the results.

My code:

public class Account
{
   private String clearPassword;
   private String encryptedPassword;
   private int key;
   private int accountId;
   private static int nextIDNum = 1000;

public Account()
   {
       this.clearPassword = " ";
       this.encryptedPassword = " ";
       this.key = 0;
       this.accountId = nextIDNum;  
       updateNextIDNum();
   }

   public Account(String clearPassword, int key)
   {
       if(clearPassword.length() >= 8 && 1 <= key && key <= 10)
       {
           this.clearPassword = clearPassword;
           this.key = key;
           this.encryptedPassword = " ";
           encrypt();
       }
       else
       {
           System.out.println("ERROR:: Minimum passwoed length should be 8.\n"
                   + "Key should be between 1 and 10.");
           this.clearPassword = " ";
           this.encryptedPassword = " ";
           this.key = 0;
       }
       this.accountId = nextIDNum;
       updateNextIDNum();
   }

   private void encrypt()
   {

       for (char letter : clearPassword.toCharArray()) {
           char shift = (char) (((letter + key) % 90) + 33);
           encryptedPassword += shift;
       }
   }

   public void setClearPassword(String clearPassword)
   {
       this.clearPassword = clearPassword.length() >= 8 ? clearPassword : this.clearPassword;
       encrypt();
   }

   /**
   * no encryptedPassword mutator method
   */

   public void setKey(int key) {
       this.key = (1 <= key && key <= 10) ? key : this.key;
       encrypt();
   }

  
   public void updateNextIDNum()
   {
       Account.nextIDNum++;
   }

   public int getAccountId()
   {
       return accountId;

   {
       return key;
   }

   @Override
   public String toString()
   {
       return "Account ID: " + this.accountId + ", Encrypted Password: "
               + this.encryptedPassword + "\t["+ key+"]:Key" ;
   }

   public static void main(String[] args) {

       Account account = new Account("Swcret#123",7);
       System.out.println(account);
   }
}
