Thread: need help 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. thank you! I think I did something wrong here is mine

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
 
 
  System.out.print("Please enter sales amount:");
 
  double sales = input.nextDouble();
 
   if (sales > 20000.01 )
 
		commission = sales * .20;
 
   else if (sales > 18000.01 && sales <= 20000)
 
		commission = sales * .18;
 
   else if (sales > 12000.01 && sales <= 18000)
 
		commission = sales * .15;
 
  else if (sales > 8000.01 && sales <= 12000)
 
		commission = sales * .12;
 
  else (sales <= 8000)
 
		commission = sales * .10;
 
{
System.out.println("Your Commission + sales total is :$" + mask.format((sales));}
}
 
}
