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.
