Basic to intermediate knowledge of Java programming
Understanding of Object-Oriented Programming (OOP) concepts (inheritance, polymorphism, abstraction, encapsulation)
Familiarity with interfaces, abstract classes, and exception handling

By the end of the training, participants will be able to apply GoF design patterns in Java projects effectively. They will know how to identify design problems, select appropriate patterns, and implement them to create extensible and maintainable software systems.

Ability to recognize and categorize design patterns (Creational, Structural, Behavioral)
Applying GoF patterns to real-world Java applications
Writing reusable, flexible, and maintainable Java code
Improved problem-solving using OOP and design principles
Refactoring existing code using appropriate patterns

Creational patterns and their use cases in Java
Structural patterns for object composition and flexibility
Behavioral patterns for communication between objects
Identifying when (and when not) to use a specific design pattern
Writing code that demonstrates understanding of multiple GoF patterns

ProgNXT Certificate of Completion will be awarded to participants who complete the course and pass the evaluations.
