CAN interface have getters and setters?
You cannot define instance fields in interfaces (they are constant – static final – values, thanks to Jon, since they’re part of the implementation only. Thus, only the getter and setter are in the interface, whereas the field comes up in the implementation. And setNumber should return a void instead of int .
Should you use getters and setters in C#?
by using getter and setter you hide the internal implementation of your class. which means in the set method of a setter, you can run a whole algorithm to parse the input data into your internal data structure. you’ll be able to later change your implementation without any impact to your users.
Can properties be declared inside an interface?
In a program if one class implements an interface then no other class in the same program can implement this interface. From two base interfaces a new interface cannot be inherited. Properties can be declared inside an interface. Interfaces cannot be inherited.
Can we define properties in interface?
Interface can contain declarations of method, properties, indexers, and events. Interface cannot include private, protected, or internal members. Interface cannot contain fields, and auto-implemented properties. A class or a struct can implement one or more interfaces implicitly or explicitly.
When to use getters and setters in an interface?
In this example, the interface doesn’t force the class to use getters and setters, I could have used a property instead (example below) – but the interface is supposed to hide these implementation details anyway as it is a promise to the calling code about what it can call.
Is the getter and setter in a class immutable?
However, for small classes or structs that just encapsulate a set of values (data) and have little or no behaviors, it is recommended to make the objects immutable by declaring the set accessor as private. For more information, see How to: Implement a Lightweight Class with Auto-Implemented Properties (C# Programming Guide).
Can you specify the property on the interface?
You can specify the property on the interface, but you can’t enforce whether getters and setters are used, like this:
How does Class C not specify the field name?
Notice how class C does not specify the field name. It is actually declared using syntactic sugar public name: string in the constructor. As Sohnee points out, the interface is actually supposed to hide any implementation details. In my example, I have chosen the interface to require a java-style getter method.
