I\'m prompting the user to enter their first and last name but I can\'t figure out how to show just their first and last initials

import javax.swing.*;
//import

    If you want to show a message box like you were doing before, this should work:

    JOptionPane.showMessageDialog(null, 
        "Your initials are " + firstName.substring(0, 1) + " " + lastName.substring(0, 1));
