Program to compute commission using two methods

Program to compute commission using two overloaded methods
I've been assigned a project. I am to compute Commission by using two overloaded methods. I have to create a class named Commission that includes 3 variables:double sales figure, a double commission rate, and an integer commission rate. Create two overloaded methods named computeCommission().
The first method takes two double arguments representing sales and rate, multiplies them, and then displays the results. The second method takes two arguments: a double sales figure and an integer commission rate. It must divide the commission rate figure by 100.0 before multiplying by the sales figure and displaying the commission. Supply appropriate values for the variables, and write a main() method that tests each overloaded method. Okay, that's the assignment! Following is the coding that I did. Where did I go wrong because when I execute this (java Commission).....I get NOTHING.
