Encapsulation in Java

→ Encapsulation is a process of wrapping data/variables with methods.

→ It helps to archive data hiding in java from outside world.

→ we can use setter and getter methods to set and get the data in it.

Advantage of Encapsulation in java

• By providing only setter or getter method, you can make the class read-only or write-only.
• Key benefit of that - Encapsulation provides ability to make changes in your code without breaking the code of others who use your code.
• By hiding implementation details, we can rework our method code without forcing a change in the code that calls your changed method.
• Encapsulation provides maintainability, flexibility, and extensibility to our application.
• Encapsulation provides more flexible and easy to change with new requirements.
• Encapsulation in Java makes unit testing easy.
• Encapsulation also helps to write immutable class in Java which are a good choice in multi-threading environment.
