Help with writing a Rational Number class

I am very new to java. Frankly, I have no idea what I'm doing. I have to define a class for rational numbers. My professor wants it all in (int) form. Also, in the class she wants us to create a method that will put the negative sign into the numerator. In the main method, it should allow you to thoroughly test your Rational number class, and it is suppose to ask the user which operation to perform, and continue to put in rational numbers till they desire to quit. I was looking here for hopefully a template to follow, but all the ones on here I guess are a farther advanced java, if that even makes sense. Or it is quite possible that I'm just slow. Anyways, for the methods for add, sub, div, and mult, my prof wants us to use void methods with with a calling object and a single argment. And all the examples I've seen on here, they used return methods. Which to me makes more sense to use a return method, but I have to do it the way she wants it. B/c you can't use return methods from void methods right? Anyways, I've been working on this for a week and I have my name at the top and the class name and then a bunch of *blinks* *blinks*. Everythiing I seem to try and do is wrong, and i'm getting pretty frustrated. So, does this make any sense to you what she's asking b/c it seems to be the exact opposite of what all the examples are on here? If anyone has some guidelines I can follow for the way she wants it, so I can make a little more sense out of it, would be greatly appreciated. Or anything really that will help me, but i'm not looking for someone to do it for me, not that anyone would. Anyways, I apologize if my ignorance in this matter is obserd, but this stuff just doesn't make too much sense to me. Thank you for your time to whom ever helps me! :)
