Third Overloaded Method Not Compiling

Create a class named Commission that includes three variables: a double sales figure, a double commission rate, and an int commission rate. Create two overloaded methods named computeCommission (). The first method takes two double parameters representing sales and rate, multiplies them, and then displays the results. The second method takes two parameters: a double sales figure and an integer commission rate. This method 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. Save the file as Commission.java

b. Add a third overloaded method to the Commission application you created in Exercise 1a. The third overloaded method takes a single parameter representing sales. When this method is called, the commission rate is assumed to be 7.5% and the results are displayed. To test this method, add an appropriate call in the Commission program's main () method. Save the application as Commission2.java

COMMISSION.JAVA

public class Commission
{
public static void main(String[] args)
{
double Sales = 10000;
double commRate = 0.075;
int rate = 7;
computeCommission(Sales, commRate);
computeCommission(Sales, rate);
}
public static void computeCommission(double Sales, double commRate)
