Midnight21, I'm sorry you're having trouble. Programming, I find, is a lot more difficult than most people expect. There's some real shell shock when you get your first exposure to it. But our problem is that your description of the assignment isn't very clear. But let's try and assess what you do know.
Do you know how to create a program? If I asked you to write a program that simply printed "Hello world!" to the screen, would you be able to do that?
Do you know how to declare variables? If I asked you to declare an integer variable named "number", assign it a value of 10, and then print that value to the screen (by referencing the variable; don't just print out the number 10), could you do that?
Do you know how to do math in Java? If I asked you to declare a variable named "bignumber", assign it the value of 1434 * 941, then print that value out, could you do that?
Do you understand how to get input from the user? If I asked you to write a program that took the value of "number" from a user, could you do that?
