1. DESIGN PATTERNS -CREATIONAL PATTERNS WATTANAPON G SUTTAPAK Software Engineering, School of Information Communication Technology, University of PHAYAO 1

2. จุดประสงค์การเรียนรู้  เข้าใจรูปแบบของแบบรูปการออกแบบทั้ง 5 ประเภท  ประยุกต์ใช้แบบรูปการออกแบบ Factory,Abstract Factory, Singleton, Builder, Prototype Pattern ได้ 2

3. CREATIONAL PATTERNS objects creation and hiding the creation logic no instantiating objects directly flexible deciding for a given use case 5 patterns 1.Factory 2.Abstract factory 3.Builder 4.Prototype 5.Singleton

4. FACTORY PATTERN most used in java create common interface create object pattern that inherited(is a) from common interface create instant object that inherited(has a) from create object pattern create new object via instant object(common) 4
