I am writing a program that allows a user to enter the name and phone-number of a contact and have the information show up as a button that when clicked, will reset the text fields to the information shown on the button.
My program does not reset the text of the of text field when the button is pressed. There are no compile-time or run-time errors. Please let me know what I am doing wrong. Thanks.
Here is the code for the CellPhone class.

Well there is a little bug in ur program. The CellPhone object in InfoButton class and CellPhone object which is running right now are not identical. They both refer to different instances of CellPhone class. Solution : Modify constructor of InfoButton class as following public InfoButton(String n, String num, String tp, CellPhone c){ name = n; number = num; type = tp;
