I am having problems designing a java program using NetBeans. The program has to be a GUI one with add note, exit note and exit program buttons. It should have a drop-down menu of courses which I can select a course and add notes during lectures, then read it back as a text file. The notes should be stored in folders by date and time. I should be able to search for key words using a search button.

So far, I have created the GUI with the various button, but the issue I am having is how to add notes, store them in folders, search etc. I am posting the codes for what I have done so far. If you could go through it and help me, I would gladly appreciate. I use NetBeans.
