Error: Could not find or load main class assessmentForSale.Calculator Caused by: java.lang.ClassNotFoundException: assessmentForSale.Calculator

i've looked into many resources and they assumed that this happens because the white spaces so i 've removed all white spaces from the code and the naming of the class might be wrong but i think mine is fine.
