It saves the extracted character in a char variable named letter.

*/

String in;

char letter;

int digit;

in = JOptionPane.showInputDialog(Enter a single alphabet);

letter = in.charAt(0);

Sample Code 2

/*

The code snippet below attempts to determine the digit corresponding to the letter.

Only a partially written Switch statement is shown. Add the additional cases.
