Actually I'm sorry for the incomplete code I guess maybe this is better.. What I want is after the algorithm is done I want to be able to print out the number output and convert the number output into letters.. Most likely just like cipher

public static void main(String args[])
    Scanner scanner = new Scanner(;
    String ct;
    String k;
    int sum = 0;

    System.out.print("Enter Text: ");
    ct = scanner.nextLine();
    int arr1[] = new int[ct.length()];

    for(int j = 0; j < ct.length(); j++)
        arr1[j] += ( (int)ct.charAt(j) - 97);
        System.out.println("Value of Text at["+j+"]: "+arr1[j]);

    //user input key
    System.out.print("Enter random word: ");
    k = scanner.nextLine();

    for(int i = 0; i < k.length(); i++)
        System.out.println( (int)k.charAt(i) - 97 );
        sum = sum + ( +(int)k.charAt(i) - 97 );
    System.out.println("Sum of all letter in the random word: "+sum);
    for(int i = 0; i < ct.length(); i++)
        System.out.print(arr1[i]+ " ");
        arr1[i] += sum;
        if(arr1[i] > 25)
            arr1[i] -= 25;
            if(arr1[i] > 25)
                arr1[i] -= 25;
    for(int i = 0; i < ct.length(); i++)
        System.out.print(arr1[i]+ " ");



Enter Text: kind
Value of Text at[0]: 10
Value of Text at[1]: 8
Value of Text at[2]: 13
Value of Text at[3]: 3
Enter random word: evil
Sum of all letter in the random word: 44
10 8 13 3 
4 2 7 22 

You could use an array of characters char[] letters = "ABCD".toCharArray();

The letter you want is at the location of your number in the array.


Would print ‘A’

This only works because you want A to start at 0 instead of 97.

Numbers To Letters (online tool), from 1-9. Once you reach 9, start back over at 1 and continue through the alphabet. Convert numbers to letters in various formats. Numbering the letters so A=1, B=2, etc is one of the simplest ways of converting them to numbers. This is called the A1Z26 cipher. However, there are more options such as ASCII codes, tap codes or even the periodic table of elements.

You can create a method:

public String getCharacterFromInt(int i) {
    return String.valueOf((char)(i + 'A'));

And you can call the method:

System.out.println("Value: "+getCharacterFromInt(0));

With 0, return A and so on.

let me know if you are trying to do something like this .

public class MainClass {
    public static void main(String[] args) {
    Scanner scanner=new Scanner(;
    String s=scanner.nextLine();
    for(int i=0;i<s.length();i++){
        System.out.println("Value of the text at ["+i+"]: "+((int) s.charAt(i)-22)%25);


if the input is:evil

Output will be:

Value of the text at [0]: 4

Value of the text at [1]: 21

Value of the text at [2]: 8

Value of the text at [3]: 11

  • You want to invert the code / logic? Well, what is the inversion of ... + " "? That is basically String.valueOf(...), try Integer.valueOf(...) for the inverse, I think you can figure out the opposite of ... - 97 on you own.
  • Possible duplicate of How do I convert a number to a letter in Java?
  • yeah something like that, but how do you do the inverse? how can you convert it back to letters?
  • To do so you will be needing the division result( (int) s.charAt(i)-22)/25 ) , so you can store it somewhere using a map may be suitable for it. then it is easy to get back the char as for 25*3+4+22=101 which is e (here 3 is division result)....i think it helps now...if it works please accept my answer.
