Creating A Commission Calculator

I need to create a simple Java program for a commission calculator with the following requirements: I need to ask the user to enter their total sales (as a double) in at the keyboard and I need to use "if" statements to tell them their commission (sales * commission rate) using the following criteria:

o < $8000 in sales – Commission rate = 10%
o $8000 to $12000 in sales – Commission rate = 12%
o $12000.01 to $18000 in sales – Commission rate = 15%
o $18000.01 to $20000 in sales – Commission rate = 18%
o > $20000 in sales – Commission rate = 20%

Then for the output the user’s Commission in a well formatted way (use the DecimalFormat class) .In comment blocks have a description of what the program does.

import java.util.Scanner;
public class CommissionCalculator
//This program calculates the commission of sales
{
public static void main(Strings[] args)
{
// create a scanner
Scanner input = new Scanner(System.in);
//define variable
double sales; //inputted sales amount
double commission = 0; //commission pay amount
