Using Java To Implement RSA Algorithm

Hi I'm looking for SOME advice on how to simulate the following:

Ive done this so far:

package RSAalgorithm;
 
public class SecurityAlgorithm {
 
     public static char[] StartSymbolic = {'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'}; 
    
     public static int[] numeric = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,
                          16,17,18,19,20,21,22,23,24,25,26};
     
    
 
     
     public static void main(String[] args) {
         
            
          long P3 = 0;
          long P3mod33=0;
          long C7=0;
           long C7mod33=0;
                         
 
        
       for(int counter = 0; counter < numeric.length; counter++){
           
            for(int i = 0; i < StartSymbolic.length; i++)  {
                
              int temp = numeric[counter];
              P3 = (long) (temp*temp*temp);
         P3mod33 = P3%33;
         C7 = (long) (P3mod33*P3mod33*P3mod33*P3mod33*P3mod33*P3mod33*P3mod33);
        int tp = numeric[counter];
                 C7mod33 = C7%33;
       }
                
                    System.out.println("*******************************************");
                     //System.out.println(StartSymbolic[i]);
                    System.out.println("Numeric: " + numeric[counter]); 
                         System.out.println("P3: " +P3); 
                     System.out.println("P3mod33: " + P3mod33); 
                      System.out.println("C7: " +C7);
                      System.out.println("C7mod33:" + C7mod33);
                    //  System.out.println(StartSymbolic[i]);
                     System.out.println("*******************************************");
           
          }
     
     }
 }

Output:

I was looking to achieve what is shown in the 1st image.

I can get the numeric, P3, P3mod33, C7, C7mod33 to print out but not the symbolic information for some reason?

I want to be able to allow the user to enter in a string then the plaintext and ciphertext can be displayed.

Like this:

String input: SUZANNE

Output:

Plaintext: S U Z A N N E
Ciphertext: 28 21 20 1 5 5 26

Thanks.
