    Question +calculateCharge():Void

    I have an assignment that asks me to write a class:


    -------------------------
    Computer
    -------------------------
    -brand:Brand
    -price:Double
    -quantity:Integer
    -totalCharge:Double
    -------------------------
    +calculateCharge():Void
    -------------------------


    I have the whole class written, I just have no clue how to add the calculateCharge, at least with it asking for void?

    Write a method called calculateCharge which has a void return type. I assume the + at the front means it is public. What specific part do you not understand?

    I guess how to code it, I have no clue how to do a void return.

    So far I have

    public double calculateCharge()
    {
     
    }

    so it would be

    public double calculateCharge()
    {
      return 0;
    }

    ?

    :headdesk:

    The main method is a void method. Surely you know what that looks like.

    See point 2 in the link above, quoted from the link:
    The return type—the data type of the value returned by the method, or void if the method does not return a value.
    See the rest of that page (and further) to see method declarations with are defined with void.

    just looking to pass a class
    To pass a class, or to learn...because these are different goals. Having a goal to learn will usually result in passing (and you come away with something), just doing something to pass and you miss out on the best part.
