I am writing a program that is suppose to show a moon lander image going up and down on a JPanel. I don't know what I am doing and have barely got anything down. Below is what I have so far. Can someone please help me at least get started on this. I am a beginning student and I am lost. I am in jeopardy of failing my class if I don't do this. I am not asking anyone to write the program for me, but I don't even know where to start.

1. Create a image object in init() method.
2. In run() method, keep changing coordinates of image (moon lander) after specific interval of time. I mean, either increment / decrement Y coordinates by a pixel to give the effect of image moving up or down. Call repaint() thereafter.
3. In paint() method, just draw the image with the changed coordinates.
