    		this.Surname=Surname;
    		this.Age=Age;

    Actually,you can write a get and set method for each attribute of Person.
    Like:
    public String getForename()
    {
    return this.Forename;
    }
    public void setForename(String Forename){
    this.Forename=Forename;
    }
    then,you can access or /and mutator whichever property of Person you want in the client code.
