Okay, here's a simple program to help you out, you'll still have to edit it.

(Toggle Plain Text)

public class arraySearch {
    public static void main(String args[]) {
        char[] alphabets = {'A', 'B', 'C', 'D'};
        int[] numbers = {4, 3, 2, 1};
        
        char userInput;
        //Code to get the user's input
        
        for(int i = 0; i < alphabets.length; i++) {
            if(userInput == alphabets[i]) {
                System.out.println(numbers[i]);
                break;
            }
        }
    }
}
