Using charAt method, won't add them as an Int, and wont print as string. Will explain better

Question

Alright, so here is my code:

import java.util.Scanner;

public class CarRental {

    public static String model;
    public static int letternum;
    public st         


        

Answer 1

Change these lines:

int one = (int) plate.charAt(0);
int two = (int) plate.charAt(1);
int three = (int) plate.charAt(2);

This will give you the actual ASCII values for the characters.

If you want something else, you'll have to subtract a constant from each of the values, as jonhopkins illustrated in his comment.

Subtract 64 to get A = 1, B = 2, etc.

I see your problem.

The algorithm is to take the ASCII values of the first 3 characters and add them to the number (the last 3 characters).

Also, you have to divide by 6 to get the letters A - E. You're dividing by 24.
