private static double stringToDouble(String stringObject);
return Double.parseDouble(stringObject.trim());
and the errors i get is
CropProfit23.java:104: 'class' or 'interface' expected
^
CropProfit23.java:105: 'class' or 'interface' expected
^
2 errors
I really don't know how to fix it. I'm extremely new at this stuff and can't get this assignment to work for class. Any help would be greatly appreciated.

Your code style is extremely poor.
This compiles and runs. Compare it to yours to see where you went wrong. - %
