Not getting anything to print out.

[warjas816]

I wrote the following code, and it seems to be working well up until the end. I do not get any error messages, but the last method has 5 lines that are supposed to print out. Nothing prints. Any ideas? Hints? Clues? Thanks!

        double squareFeet;      //number of square feet per room
        double totalSquareFeet; //total square feet for the job
        double gallons;         //number of gallons required for the job
        double costGallon;      //cost per gallon of paint
        double labor;           //number of labor hours required for the job

hint:
your "displayResults" method is defined nicely but never called in your main method!

If I wasn't so tired I'd elaborate, but you did say you wanted just a hint!
hint: indenting is nice also!
edit: hint hint: code tags are fun too!

fix it up and show it again!!

[warjas816]

Thanks so much! I got it all to work now. I added the code tags, and the actual code is all indented, but when I copy and paste it here, it loses the indents. Is there a better way to cut and paste?
Here it is without the indentations transferring.
