What is Interface Segregation Principle in Java?
This principle was first defined by Robert C. Martin as: “Clients should not be forced to depend upon interfaces that they do not use“. The goal of this principle is to reduce the side effects of using larger interfaces by breaking application interfaces into smaller ones.
Why is dependency inversion important?
Dependency inversion well applied gives flexibility and stability at the level of the entire architecture of your application. It will allow your application to evolve more securely and stable.
What do you need to know about the Interface Segregation Principle?
The Interface Segregation Principle (ISP) states that a client should not be exposed to methods it doesn’t need. Declaring methods in an interface that the client doesn’t need pollutes the interface and leads to a “bulky” or “fat” interface. Reasons to Follow the Interface Segregation Principle
What does the segregation principle in ISP mean?

What does the segregation principle mean in Java?
In this tutorial, we’ll be discussing the Interface Segregation Principle, one of the SOLID principles. Representing the “I” in “SOLID”, interface segregation simply means that we should break larger interfaces into smaller ones. Thus ensuring that implementing classes need not implement unwanted methods.
How are interfaces segregated in a coffee machine?
And the EspressoCoffeeMachine interface also extends the CoffeeMachine interface, and defines the brewEspresso method. Congratulation, you segregated the interfaces so that the functionalities of the different coffee machines are independent of each other.
