Salary of each sales person

The following file has the problem and the solution, however I can getting the following error "cannot find symbol variable math" when compiling. Where am I going wrong at?

(Sales Commissions) Use a one-dimensional array to solve the following problem: A company pays its salespeople on a commission basis. The salespeople receive $200 per week plus 9% of their gross sales for that week. For example, a salesperson who grosses $5000 in sales in a week receives $200 plus 9% of $5000, or a total of $650. Write an application (using an array of counters) that determines how many of the salespeople earned salaries in each of the following ranges (assume that each salesperson's salary is truncated to an integer amount):
1. $200-299
2. $300-399
3. $400-499
4. $500-599
5. $600-699
6. $700-799
7. $800-899
8. $ 900-999
9. $1000 and over
Summarize the results in tabular format

Code:

// Determining how many sales person earn salaries
public class Salary
{
    public static void main (String args [])
    {
        // intializer list specifies the integers amount
        double salary [] = { 0, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200};
        int value []= new int [11];
        System.out.printf( "%s:%20s:\n", "Index", " Value"); // column heading
        
        for (int index = 0; index < (salary.length); index++)
        {
           if (10<=(int)math.floor(((salary[index]*(.9)+200)*.01)))
               ++value[10];
               
            else 
               ++value[(int)math.floor(((salary [index]* (.9)+200)*.01))];
        } 
            
        for (int index1 =2; index1<value.length-1; index1++)
           System.out.printf("$%5d-%5d: %10d\n",
           index1 *100,index1 * 100 + 99, value[index1]);      
        

        // output each salary element's value.
        for (int index2 =11; index2<= value.length; index2++ )
             System.out.printf( "$%5d%5s: 20d\n", index2*100-100, "& more", value[10]);

    } // end main
} // end class Salary

The class is called Math no math , :gOOd:

Code:

public class Salary
{
    public static void main (String args [])
    {
        // intializer list specifies the integers amount
        double salary [] = { 0, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200};
        int value []= new int [11];
        System.out.printf( "%s:%20s:\n", "Index", " Value"); // column heading
       
        for (int index = 0; index < (salary.length); index++)
        {
           if (10<=(int)Math.floor(((salary[index]*(.9)+200)*.01)))
               ++value[10];
               
            else
               ++value[(int)Math.floor(((salary [index]* (.9)+200)*.01))];
        }
           
        for (int index1 =2; index1<value.length-1; index1++)
           System.out.printf("$%5d-%5d: %10d\n",
           index1 *100,index1 * 100 + 99, value[index1]);     
       

        // output each salary element's value.
        for (int index2 =11; index2<= value.length; index2++ )
             System.out.printf( "$%5d%5s: 20d\n", index2*100-100, "& more", value[10]);

    } // end main
} // end class Salary

Your reply is confusing. The class is salary and not math. Please explain further. Thanks

In your code you wrote :

Code:

if (10<=(int)math.floor(((salary[index]*(.9)+200)*.01)))

and must be

Code:

if (10<=(int)Math.floor(((salary[index]*(.9)+200)*.01)))

you used the class "math" .Must be "Math".
