Hello. My name is AxeFalador. I am a newcomer to Java programming.
Now, on to what I need help with.
I'm currently working on my very first fully function Java Swing GUI Application, using Matisse on NetBeans 5.0.
I am writing your basic "electronic magic 8-ball" GUI, with the goal that the user types in a yes/no question in a JTextField, and clicks a JButton, and the program displays, in a separate JTextPane, an answer randomly chosen from a pool of pre-composed answers.
I have programmed a few basic functions into the GUI, but I can't get the last few bumps rolled out, so to speak. I have a fully functional exit button, and the "Ask..." button (the JButton that's supposed to generate the random answer in the separate JTextPane) has only one answer it can display in the JTextPane. I can't seem to figure out just how to make the JTextPane display randomly selected answers when the "Ask..." JButton is clicked. I can only figure out how to display a single answer.
Here is what I have for code, so far (most of it was automatically generated by NetBeans' Matisse GUI Builder):
Any tips, help or advice you could give me would be greatly appreciated!
