So when i try to compile this, the variables numberOfTopping, areaOfPizza, and sizeOfCrust are all causes of errors because "they aren't initialized", but i have have defined them all as doubles and set numberOfTopping as keyboard.nextDouble and given the other 2 formulas, any help would be appreciated.
