Howdy guys.
i am working on a homework assignment that requires us to create somewhat of a working cellphone.
i have my code written out and it works partially. the textpanel is supposed to display the numbers pressed like this xxx-xxxx for a local number called and x-xxx-xxx-xxxx for a long distance called, and shows up as invalid number on the screen when the numbers entered do not match that criteria.
mine however only shows one number on the screen when i press a button and so always shows up as an invalid number and i do not know what i have done wrong.
i will post my entire code here in a second minus the main class because all it has is the new CellPhone() tag to run the program.
i will warn you. i am a big newb on coding and so my code is clunky and i apologize right now for that, but i have to start somewhere and i know i will get better with practice, but if someone would be able to take a look at my code and point in me in the right direction i would be much appreciated.
here is my code
Code:
package cellphone;
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
import java.awt.Color;

public class CellPhone extends JFrame {

//Creates the controls for our GUI

//creates the buttons for the cellphone
