Pola Builder ngonstruksi obyek kompleks selangkah demi selangkah, misahake konstruksi saka representasi. Pola iki minangka katrangan kanggo obyek kanthi pirang-pirang parameter utawa bagian opsional, ngasilake konstruksi obyek sing bisa dibaca, fleksibel tinimbang konstruktor sing ora gampang.
Masalah sing dipecahake Builder
Objects with MANY parameters (especially optional ones) lead to problems:
✗ huge constructors: new Pizza('large', true, false, true, 'thin', false, ...) →
unreadable (which boolean is what?); hard to use; error-prone
✗ many constructor overloads (telescoping constructors) → messy
→ Builder provides a clean, readable, step-by-step way to construct such objects.
