I dont see what i do wrong here.

Question

Hi
I have a bit of a problem here. Im trying to create an object in my test class. However, Since i have some parameters in my constructor i get an error message in the test class:
Error(8,27): no declaration allowed here, use '{'
and
Error(8,34): , expected
If i remove the parametrs from the constructor, I dont get any errors. Thing is, I think there should be parameters in the contructor since its parameters that the object always has.
Here is the Classes contructor code:
public Kund(String nummer, String namn, String adress){
    order=new HashMap<String, Order>();
    setNummer(nummer);
    setNamn(namn);
    setAdress(adress);
}and here is the code from the testclass when im trying to create and object:
public static void main(String[] args) {
        Kund k = new Kund(String nummer, String namn, String adress);
        k.setNummer("125");
        k.setNamn("Peter");
        k.setAdress("Lund");and as stated above these are the error messages i get:
Error(8,27): no declaration allowed here, use '{'
Error(8,34): , expected
Anyone have a pointer to what im doing wrong?

On that note though..Why having both parameters and then also set and get methods in the class? Seemes like double code for the same thing.It is. It is often done for flexibility and convenience: you can either pass the values to the constructor, or use a no-argument constructor and set the values later, if you wish.
You can also use the setters to change the values, if someone's address changes for example.
