Design Patterns (GoF) for Java Training in Metro Manila, Philippines

This training program introduces the Gang of Four (GoF) design patterns and their application in Java. Participants will learn to identify recurring design problems, apply the correct patterns, and implement them in Java code. The course blends theory, examples, and hands-on coding exercises to strengthen object-oriented design and improve maintainability, scalability, and reusability of software.

Foundations and Creational Patterns

Module 1: Introduction to Design Patterns

• History and importance of GoF patterns

Module 2: Creational Patterns Overview

• Intent and benefits of Creational patterns
• Factory Method
• Abstract Factory
• Builder
• Prototype
• Singleton

Module 3: Hands-on with Creational Patterns
