Else-Without-If and Other Issues That Don't Make Sense

[ssrock64]

Hello, everyone. I'm writing a program to generate a cipher alphabet and to allow the user to create a ciphered message or attempt to decipher another, and the compiler keeps throwing up an Else-Without-If error where I find none no matter how much I look. Here's the main class, in which the error traces to line 78:

import java.io.*;
import java.util.*;
public class CipherTester
{
  
  static final String[] baseAlphabet = {"a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"};
  
  static Scanner in = new Scanner(System.in);
  
  static String cipherDecipher;
  
  
  
  public static void main(String[] args)
  {
    
    System.out.println("Do you wish to create a cipher message (y/n)?");
    
    cipherDecipher = in.nextLine();
    
    if(cipherDecipher.equalsIgnoreCase("y"))
    {
    
      Cipher cipher = new Cipher(baseAlphabet);
    
      cipher.createCipherAlphabet();
    
    }
    
    else if(cipherDecipher.equalsIgnoreCase("n"));
    {
              
      System.out.println("Do you wish to decipher a message (y/n)?");
      
      cipherDecipher = in.nextLine();
      
      if(cipherDecipher.equalsIgnoreCase("y"))
      {
        
        Decipher decipher = new Decipher(baseAlphabet);
        
        decipher.createCipherAlphabet();
        
      }
      
      else if(cipherDecipher.equalsIgnoreCase("n"))
      {
        
        System.out.println("You have chosen not to perform any action.");
        
      }
      
      else
      {
        
        System.out.println("You did not enter a valid option. Re-start program and try again?");
        
        cipherDecipher = in.nextLine();
        
        if(cipherDecipher.equalsIgnoreCase("y"))
        {
          
          main(args);
          
        }
        
        else
        {
          
          System.out.println("Done.");
          
        }
        
      }
      
    }
    
    else
    {
      
      System.out.println("You did not enter a valid option. Re-start program and try again?");
        
      cipherDecipher = in.nextLine();
        
      if(cipherDecipher.equalsIgnoreCase("y"))
      {
          
        main(args);
          
      }
        
      else
      {
          
        System.out.println("Done.");
          
      }
      
    }
    
  } 
}

And here's the unfinished class it references (both referenced classes are identical at this point):

import java.io.*;
import java.util.*;
public class Cipher
{
  
  String[] myBaseAlphabet;
  
  String[] myCipherAlphabet;
  
  
  
  public Cipher(String[] baseAlphabet)
  {
    
    myBaseAlphabet = baseAlphabet;
    
    myCipherAlphabet = new String[myBaseAlphabet.length];
    
  }
  
  public void createCipherAlphabet()
  {
    
    Random rn = new Random();
    
    for(int i = 0; i < myBaseAlphabet.length; i++)
    {
      
      myCipherAlphabet[i] = myBaseAlphabet[rn.nextInt(myBaseAlphabet.length)];
      
      System.out.print(myCipherAlphabet[i] + " ");
      
    }
    
  }
}

I include the second class, too, because when I remove the error-causing else from the main class and run it to test the rest of the program, the output for creating a cipher alphabet acts strangely, creating and displaying the alphabet as intended, but then running the decipher prompt, too. To be clearer, here's exactly what it displays:

Do you wish to create a cipher message (y/n)?
[DrJava Input Box, answered "y"]
s v b q k y e h n l z w w x y t b s l l v e d x t v Do you wish to decipher a message (y/n)?
[DrJava Input Box]

I feel that this odd behavior is possibly related.

Any ideas?

else if(cipherDecipher.equalsIgnoreCase("n"));

You've done the common trick of putting a semi-colon at the end there.

Remove that and that should compile (barring other errors).

Thanks! Usually I catch that the moment I type it, but I was in a bit of a rush today because I realized it's Monday, not Sunday and that the program is now officially late.
