Printing all variables value from a class

I have a class with information about a Person that looks something like this:

public class Contact {
    private String name;
    private String location;
    private String address;
    private String email;
    private String phone;
    private String fax;

    public String toString() {
        // Something here
    }
    // Getters and setters.
}

I want toString() to return this.name +" - "+ this.locations + ... for all variables. I was trying to implement it using reflection as shown from this question but I can't manage to print instance variables.

What is the correct way to solve this?
