Problem using a JButton object(s)
hello.
Im having difficulty trying to display 2 buttons inside a TitledBorder within a tab. when i run the following program, the Exit the system button is only displayed in the Existing User tab. the Exit the system button is supposed to appear in 3 tabs and not one. the variable names for the jbExistingUserLogOn and jbExitTheSystem objects are almost identical. should i change the variable name of the jbExitTheSystem object from jbExitTheSystem to jbQuit? or do I have to create a separate tab that would allow the user to exit the system?
