When should you prefer classes and when should you avoid it?

In Java, classes are a fundamental part of Object-Oriented Programming (OOP). They allow you to encapsulate data and methods, promoting code reusability and modularity. However, there are instances where using classes may not be the best choice. Below is an explanation of when to prefer classes and when to avoid them.

When to Prefer Classes:

• Encapsulation: When you want to bundle data and methods that work on that data together.
• Code Reusability: When you need to create multiple instances of similar objects, such as in a game with different characters.
• Inheritance: When you want a new class to inherit properties and behaviors from an existing class.
• Polymorphism: When you require methods to perform different tasks based on the object that invokes them.

When to Avoid Classes:

• Simple Scripts: For small scripts or one-off tasks, using primitive methods might be simpler and more efficient.
• Performance Sensitivity: In performance-critical applications, the overhead of object creation may be undesirable.
• Global Functions: When utility functions do not need to be associated with an object, consider using static methods or functions.
