i am a student and taking an intro to computer science class....i have NO IDEA how to write java nor did i have any idea that this was going to be involved in the class.....my assignment is as follows: write a program that reads in the numerators and denominateors of two fractions. The program should print the product of the two fractions as a fraction and as a percent.

Granted that seems easy for most of you more than likely......i have NO clue how to do this and this is only in chapter two so i am kind of nervous as to what else will be involved in the class......any tips on what books or anything else i could use would also be greatly appreciated........thank you!!!!!!!!
