Thread: Extensive help with banking simulator

Do you have any specific questions about your assignment?
Please post your code and any questions about problems you are having.

It's a huge bunch of questions, I really don't know where to start...I'll try with something.

This is the customer class. It is my first attempt of doing class with a constructor, so I really don't have any idea of what I'm doing... Down at the get-method, I get an error stating "Cannot make a static reference to the non-static field pNr". Why is that? (Btw, pNr stands for "person-number", it's birth date + four digits, like mine is 940430-4322. It's a Swedish thing.)

public class Customer {
 
	private static String name;
	private long pNr;
 
	public Customer (String n, long p){
		name = n;
		pNr = p;
	}
 
	public static void setName(String n){
		name = n;	
	}
 
	public void setPNr(long p){
		pNr = p;
	}
 
	public static String get(){
	String namePNr = (name+"\t"+pNr);		
		return namePNr;
	}
}

Cannot make a static reference to the non-static field

All the variables and methods in the class should not be static. Remove the static.
static is used when there will only be one variable that will be shared by all instances.
non static variables only exist in an instance of the class and can not be used by static methods.

Please edit your post and wrap your code with
[code=java]
<YOUR CODE HERE>
[/code]
to get highlighting and preserve formatting.

Customer.get();

Instead of using the name of a class: Customer, use a reference to an instance of the Customer class.

I'm assuming Customer is a class and that get() is a method in the Customer class.

You should not be using static for anything. The one exception is the main() method.
