Hi all,

Holiday h1 = new Holiday("Hull", 14, 8);
Holiday h2 = new Holiday("Bermuda", 2, 800);
Holiday h3 = new Holiday("Los Angeles", 19, 1900);
h3.setcost(2100);

How could we possibly help without knowing how Holiday class is defined?

Where does the error occur, and what is the definition of the class and the method throwing the error?

sorry about that the holiday class is public ArrayList<holiday> Hols = new ArrayList<>(); // Creates an array list called Hols uses object Holiday to fill it

public Holiday(int NewDuration, String NewDestination, int newcost) { // Creates a method called Address with two variables (NewNumber / NewPostcode)
Duration = NewDuration;
Destination = NewDestination;
cost = newcost;

and what do you mean by definition of the class and method throwing the error

Your parameters are in the wrong order. You have int, String, int, but in your constructor you are passing a String as the first one.

Solution 1

Check the definitions of the Holiday constructor, and the Holiday.SetDestination methods (depending on which line the error occurs on).

In the first case, you need a constructor that takes three parameters: string, int, int
In the second, you need a version that take a string, not an int.

Do you have a constructor that takes no parameters? If not... :laugh:

Adamdew93 25-Jun-15 6:15am

I dont think I do haha but how should it be coded if you can give me an example that would be excellent

OriginalGriff 25-Jun-15 6:26am

If you don't have a constructor that takes no parameters, then you can't construct it!
You need to create a constructor, and have it set "dummy" values - or use the parameterised version you use in the other code.
