New to Java

I'm a beginner in JAVA. I've just started learning JAVA a few days ago but I need to do an applet in a week time. I need an applet that can record users' voice and store the audio in a buffer (so it won't store anything in users' hard disk). Then users can listen back to their recorded speech. The applet doesn't need to have GUI but the main functions (i.e. Record, Stop & Play) can be accessed by JavaScript. The actual interface (with record, stop & play buttons) is done in Flash. So the buttons in Flash will call the necessary JavaScript to perform the functions. Both the applet and Flash file will be embedded in the same HTML file. I'm really confused as where to start and would appreciate it if someone can shed some light. Thanks a lot.
