JComponents arent displayed properly unless the window is minimized and reopened
I just want an answer and want to make this program work
Be very careful what you wish for...
The following makes use of the following concepts...
- Creating a GUI With Swing
- Laying Out Components Within a Container* How to Use CardLayout
- Dependency Injection in Java
- Observer Pattern
The example is also incomplete and you're going to need to take the time to understand the above concepts in order to fill out the missing parts
I also think you're going to want to have a look at How to Use Tables at some point.

Side by comparison of your output (left) and mine (right)
Beside also getting reusability for free, imagine your client comes back and says, "I want to change the font" or even worse, "I just want to change the font on these few elements".
Which approach do you think will cope better?
Or, you get some user like me, whose blind as a bat and has the font accessibility of the system ramped right up?
