java - How to calculate multiple user input (IF statements ) to return a total -

good morning/afternoon,

i'm having issue code works fine, aside exception handling course has not reached staged please omit these functions. setup variable used calculate total bill, when compiling keeps saying "floodsort" , "pipesort" not initialized.

i tried using separate if statements assign value of variable, perhaps not correct way. attempted full set of if statements written in comment under program. not return desired results. same scenario variables not initialized.

question: best way return customers total bill?

i extremely excited , grateful assistance on previous post, assistance or suggestions appreciated. i'm taking online classes because none offered in person best can get!

there no guarantee of if statements hit. since don't assign initial values floodsort , pipesort may never initialized. if want sure initialized can set them 0 @ start

 double floodsort = 0;  double pipesort = 0; 

if rewrite code use arrays instead of separate variables this
