Thread: Having java return method problem

getFullAddress() should return the address as a formatted String, one item per line:
e.g. 23 High Street
Newcastle
NE1 1NE // There should be a space between the two parts of the postcode.

how i can get done of this return?

public class Address
{
    private String postcode;
    private String street;
    private String town;
 
    /**
     * Constructor for objects of class Address.

The problem is "street/n" as well as "town/n" it should be "street\n" and "town\n"! That's why you don't get any spacing!

Regarding:

    public String getFullAddress()
    {
        String fullAddress = "street/n" + "town/n" + "postcode";
        return fullAddress;
    }

you appear to be returning hard-coded Strings and not the data held by the object of this class. Instead of "street/n" why not call getStreet() + "\n" or street + "\n" (no quotes around street), and the same for the other items.
