Object Oriented Design courses can help you learn principles like encapsulation, inheritance, and polymorphism, along with design patterns such as Singleton and Factory. You can build skills in creating reusable code, improving software maintainability, and designing systems that are easier to understand and extend. Many courses introduce tools like UML for modeling, as well as programming languages such as Java and Python, which are commonly used to implement object-oriented concepts in real-world applications.
