    Default Need help with what to do next

    Okay, so below is my code at this point. What I need to do is to get some help with my text fields. I have two jtext fields as you can see by my code. In these two two text fields the user will put in the hours they worked in the first one, and the amount they earned in the second one. There is a button labeld ENTER that is supposed to write these two pieces of information to my array. I cannot figure out how to create this action.

    a) Please wrap your code in the code tags
    b) For writing the action from your first post, see How to Write an Action Listener (The Java™ Tutorials > Creating a GUI With JFC/Swing > Writing Event Listeners)
    c)
    public FrameMain(0 {

    Incorrect syntax. I suggest you read and study the syntax in the following tutorial:
    Classes (The Java™ Tutorials > Learning the Java Language > Classes and Objects)
