Hi,
Thankyou for the previous helps.
I am trying to make autmatic door system , which has some buttons on it and a JTextField at bottom , if the user enters correct the four digit then the JTextField's color turns to green else to red. and by defualt the color the JTextField is black.
I have just made the design and all my codes are in single class, now trying to complete the functuinality and then separating the classes. Now with previous helps , I have synchronized the events of four buttons at some level , but not satisfactory.
All your comments and the hlep will be much appreciated.
Code is mentioned below for more suggestions:-
Regards,
