Abstraction vs Encapsulation in Java - Key Differences

One of the key distinctions in Java programming is the difference between abstraction and encapsulation. These concepts are fundamental in object-oriented programming and play a crucial role in designing robust and maintainable software.

Abstraction in Java

Abstraction in Java is the concept of hiding implementation details and showing only the essential features of an object. It allows developers to create a simplified view of a complex system. This is achieved through abstract classes and interfaces, which define a set of methods without implementing them.

Encapsulation in Java

Encapsulation in Java involves bundling the data (attributes) and methods (behavior) that operate on the data into a single unit (class). By encapsulating data, you can control access to it and prevent unauthorized modification. This enhances the security and maintainability of the code.
