This coding practice called Computer Talk wants me to cast letters as numerical value but I have no idea what its talking about

Question

It starta off like this but I haven't been taught the function of char or why we're even using char.at when I only know to use it for arrays. It seems like it should be simple but it just seems complicated in this state.

import java.util.Scanner;

class Main
{
public static void main(String[] args)
{
Scanner read = new Scanner(System.in);
char a = read.next().charAt(0);

//your code goes here

}

Answer 1

You can do casting to numerical value like
System.out.println( (int)a );
This will print ASCII value of char a.
But am not fully umderstood the problem. Posting full description may helps..
Hope it helps..
