A while back I started a project that soon built up a shed load of code, most of the code was made up of components and their properties. All was going well until I hit an error. Off the top of head, the error was something on the line of exceeding the code limit of a constructor, roughly 65000 bytes.
This error has literally bought me and my project to halt. At the same time I have also found major problems in my understanding of SWING.
What I tried was to break my game code into logical sections, putting each section into a different class. For example, a jpanel which dealt with buying and selling would be its own .java file. Another jpanel that dealt with shipping would be in another .java file.
What I hoped to achieve was a JFrame that called each of these jpanels when the user requested it at the press of a jbutton. However, this didn't quite work as I wished, putting me in a position where I need help.
What I have done is simplified my problem by creating an example framework, hoping that somebody could point out what I need to be looking at, possibly even a solution.
I have created a JFrame which holds a panel called bg, which itself holds 2 JButtons (btn1 and btn2). In a different class file I have created a JPanel called panel1, and in another class again I have created another JPanel called panel2.
When the user opens the application they are presented with a frame and the option of two buttons, when any of these buttons are pressed I would like for either panel1 or panel2 to open. How would this be done?
Any help would be greatly appreciated. Thanks in advance.
