We can have a abstract class for Printer which will implement the methods like Print, Scan and Fax. Declaring methods in an interface that the client doesn’t need pollutes the interface and leads to a bulky or fat interface. In our example, we’ll separate the operations into distinct interfaces: class SpellCheckable(ABC): abstractmethod def checkspelling (self. What Is the Interface Segregation Principle The Interface Segregation Principle (ISP) states that a client should not be exposed to methods it doesn’t need. Suppose we have to design a system for Printers in which we have to implement different types of Printers like LaserPrinter, InkJetPrinter, LEDPrinter, 3DPrinter. Interface Segregation Principle (ISP) The Interface Segregation Principle recommends creating specific interfaces for clients to avoid unnecessary dependencies. Lets take an example to understand the above with a Printer System Example. In simple terms, an interface should only contain methods that are relevant to the clients that use it and they should not be forced to implement methods that they don’t need. Interface Segregation Principle states that “ Clients should not be forced to depend on methods that they don’t need.” In object-oriented terms, an interface is represented by the set of methods and properties an object exposes. If you have not gone through this, you can see them from the below links Interface Segregation Principle The interface segregation principle (ISP) provides some guidelines for an idea that we have revisited quite repeatedly already: that interfaces should be small. In this series, we have already discussed about the first three principles of SOLID. Understanding the Interface Segregation Principle of the SOLID Object Oriented Programming principles will improve the quality of the software you write. From a coding perspective, writing an interface is simple. Next, an example of a fat interface is picked for a use case in Java, it is analysed and then refactored in line with the interface segregation. It first looks at the definition of the interface segregation principle and explains its concepts. The Interface Segregation Principle states that clients should not be forced to implement interfaces they don't use. In this article, we will talk about “I” in SOLID i.e. Interface Segregation Principle Interfaces form a core part of the Java programming language and they are extensively used in enterprise applications to achieve abstraction and to support multiple inheritance of type- the ability of a class to implement more than one interfaces. This tutorial explains the Interface Segregation Principle with example in Java. If you are following the Software Design Principles while developing an application, the first thing that comes to your mind is the Interface Segregation Principle. This is the 4th part of the series “ Understanding SOLID in C++”.
