Implementing Dependency Injection Using Method Injection using System;namespace DependencyInjection{publicinterfaceIEmployeeService{voidServe();}// Initialize Employee1publicclassEmployee1:IEmployeeService{publicvoidServe(){Console.WriteLine("Employee 1 is Initialized.");}}// Initialize Employee2publicclassEmplo...
we are implementing asetter dependency injection. See, the Manager class calls a method of Accountant class by using the Accountant class object which is instantiated inside a setter method. See the example below.
Setter Injection:Worst. When we have a large number of fields, the setter methods cause a focus shift. Immutability In Software Programming terms, an Object is called Immutable if, by any means, its state can not be modified after creation. Immutability is a really important principle of good...
The dependencies are typically passed in through the object’s constructor, setter method, or interface.This makes the object loosely coupled and easy to test. Benefits of Using Dependency Injection: Loose coupling: Objects are not tightly coupled to their dependencies, making it easier to maintain...

ENDIF. ENDMETHOD. And a setter method is needed to inject the switchable instance: method SET_SWITCHABLE. mo_switchable = io_switchable. endmethod. These two classes and one interface are put to the following package: Consumer code – version one without using dependency injection Here the ZCL...
