" '.class' expected

I am getting .class expected at debugging for line 16 "sale = input.nextDouble[ ]

import java.util.Scanner; // program uses class Scanner
 
public class SalesCommission
{
    public static void main( String args[] )
    {
        // create Scanner for input from command window
        Scanner input = new Scanner( System.in );
 
        double sale[] = { 200-299,300-399, 400-499, 500-599, 600-699, 700-799, 800-899, 900-999, 1000-9999 };
 
        System.out.println( "Enter gross sales amount: " ); //prompt  user for input
        sale = input.nextDouble[];
 
        // find commission for individual salary range
        for ( int counter = 0; counter < sale.length; counter++ );
        {
            // output salary range
            if ( sale == 1000 )
                System.out.print( "%3f-%3f: ",
                sale[8] = sale[8] * .09 + 200 );
            else
                System.out.print( "%3f-%3f: ",
                sale[8] = sale[8] + 1 );

Use () instead of []

Tried ( ) originally and again; got error for that line and additional errors.

oh wait. You're misunderstanding the array
{ 200-299,300-399, 400-499, 500-599, 600-699, 700-799, 800-899, 900-999, 1000-9999 };
gives you an array
{ -99, -99, -99, -99, -99, -99, -99, -99, -8999}
as it treats - as minus or subtract.


You need a secondary double variable to set the output to.
I would set your array to be the lower limits, eg
{ 200,300, 400, 500, 600, 700, 800, 900, 1000};

Your comparison method will have to change as well.

Unfortunately, our assignment calls for 200-299, 300-399, etc. I have since tried something that will list the salaries, if I remove " sale = input.nextInt ". However, I cannot enter salaries and complete the other requirements of calculating bonuses. Thanks anyway!

You can't store ranges in a double array. Either find a class that stores ranges and lets you compare them easily, or use a different loop to find where within the range it fits.

eg:
if sale >= 1000
On second thought, make it an int array:
int[] saleRange = { 200,300, 400, 500, 600, 700, 800, 900, 1000, 10000};
The range of the i'th element is
saleRange[i-1] to (saleRange[i]-1)
