    geteggPrawn is undefined for pizza
    The compiler is usually correct. Check why.

    Without definitions and code, I can't see what is wrong.

    eggPrawn.eggPrawn.seteggPrawn
    That is unusual looking and confusing code.
    If you don't understand my answer, don't ignore it, ask a question.

    Yeah but the compiler is telling me that "The method geteggPrawn() is undefined for the type Pizza" yet it works for the other without an error, even though i don't have get method in pizza, it's in another class. Why would it work for one but not the other?

    Only answer without seeing the code is that it is coded correctly in one and incorrectly in the other.

    Why does the compiler find an error?

    Do you know why

    	boolean vegetarian = true;
    				if (bacon.getType().equals("bacon")||(prawn.getType().equals("prawn"))) {
     
    				 vegetarian = false;
    				  System.out.println("This pizza is not Vegetarian");
    			}
     
    				else {
     
    			     System.out.println("This pizza is Vegetarian");
    				}
    will work when bacon and prawn are selected, it will say this is not vegetarian, however if i say no to bacon and prawn and choose e.g. cheese it'll crash and won't appear with "this is a vegetarian pizza"

    it'll crash
    You should post the full text of the error message
    AND the code that causes the error.

    Exception in thread "main" java.lang.NullPointerException
    at PizzaChoice.main(PizzaChoice.java:150)

    and if (bacon.getType().equals("bacon")||(prawn.getType() .equals("prawn"))) {

    sorry about that

    Do you know of anyway to say if the user selects an option then they can't select any others?
    for example
    do you want coke
    do you want fanta
    if they choose coke then fanta becomes unavailable, creating an illegal argument exception
