How many constructor arguments is too many?

        return this;

    public CustomerBuilder withSSN(String ssn) {
        this.ssn = ssn;
        return this;
    }

    // client doesn't get to instantiate Customer directly
    public Customer build() {
        if (surname == null || firstName == null || ssn == null) {
            throw new NullPointerException("Incomplete customer definition");
        }
        /* option 1: would have package private setters */

        target.setSurname(this.surname);
        target.setFirstName(this.firstName);
        target.setSSN(this.ssn);
        return target;

        /* option 2:

        I actually like the approach marcio suggests, where we pass the
        builder in the constructor - prevents the need for all of the
        setters

        Customer target = new Customer(this);
        return target;
