    Your code should look like this
    @ jocdrew21 Not quite. The code in post#3 is missing all its indentations.
    If you don't understand my answer, don't ignore it, ask a question.

    Norm I just cute a pasted his code showing him what it should look like. Obviously once he does that from his JDK it will naturally do it for him. Correct?

    Default How to place the chosen pizza size in a integer variable.

    //set price and size of pizza ordered

    if (inches==10)
       System.out.println("Cost 10.99\n");
     
    else if (inches==12)
       System.out.println("Cost 12.99\n");
     
    else if (inches==14)
       System.out.println("Cost 14.99\n");
     
    else if (inches==16)
       System.out.println("Cost 16.99\n");
     
    keyboard.nextLine();

    I hope that my formatting is better? The value I get here will eventually be added to other totals in my program.

    Hello GregBrannon, I'm new to this site and as you have probably deducted already, I'm new to programming. I appreciate your guidance on the proper way to conduct myself on this site.

    I hope my second post has a better formatted to it. I'm trying to get assistance with this java issue. Could you help me with this issue. I'm not sure if you are an administrator of this site or just one of the many programming experts. In either case I sure hope this site is able to help me.

    One weakness I see for the code in post#7 is that the {}s that should surround the code inside of an if statement are missing.

    What problems are you having with the code? Can you explain in more detail and ask some specific questions?
    If you don't understand my answer, don't ignore it, ask a question.
