Calling a method within an application?

Question

Hi I'm a student taking an intro Java class and right now I have to develop and application that prompts for someone to input a character of the alphabet and it will display the corresponding number on a telephone that it is listed under. The main method gets the input from the user and we are required to retrieve the corresponding digit to the character from a separate method using either a switch statement or a nested if-then-else statement to determine what the digit is. I'm having trouble calling that method in the main class which is another requirement. any suggestions?
public class Hmwk08
     * Main driver begins program execution.
     * @param args program arguments
    public static void main(String[] args) throws Exception
        char letter;
        char ch;
        int relatesTo;
        PrintStream win = new PrintStream(System.out);
        Scanner in = new Scanner(System.in);
        String newLine = System.getProperty("line.separator");
        win.println("Given a letter of the alphabet, this program" + newLine
                    + "will tell you the corresponding digit on a" + newLine
                    + "telephone keypad.");
        win.println();
        win.print("Enter a letter: ");
        letter = in.nextLine().charAt(0);
        letter = Character.toUpperCase(letter);
     * Get the digit on a telephone keypad that corresponds
     * to the specified character. If the character is neither
     * a letter nor a digit, this method will retun the
     * asterisk character: '*'
     * @param letter the specified character
     * @return the corresponding digit
    private static char getPhoneDigit(char letter)
        char digit;
        digit = '*';
        if(letter == 'A' || letter == 'B' || letter == 'C')
            digit = '1';
        return digit;
}

Answer 1

Your method is static so you can call your method without creating a Hmwk08 object.
char result = getPhoneDigit(letter);Would suffice in your main method
