Why getters and setters are not public variables?
Main problem with making field public instead of getter and setter is that it violates Encapsulation by exposing the internals of a class. Once you are exposed internals of class you can not change internal representation or make it better until making changes in all client codes.
Should getters and setters be public or private?
Usually you want setters/getters to be public, because that’s what they are for: giving access to data, you don’t want to give others direct access to because you don’t want them to mess with your implementation dependent details – that’s what encapsulation is about.
Why do we use getter and setter methods in a class?
Getters and setters are used to protect your data, particularly when creating classes. For each instance variable, a getter method returns its value while a setter method sets or updates its value. Getters and setters allow control over the values.
Should getter methods be private?
The reason for declaring the getters and setters private is to make the corresponding part of the object’s abstract state (i.e. the values) private. That’s largely independent of the decision to use getters and setters or not to hide the implementation types, prevent direct access, etc.
Why do we need a getter and setter?
Why is it not recommended to make all of a classes variables public?
Public variables in general in a class are a bad idea. Since this means other classes/programs, can modify the state of instances.
Have you used private variables with getter setters Why do you need them?
The setter method sets a value to the private variable which can’t be done when it’s from another class. So basically the getter-setter methods are for when you are trying to access or modify private variables from another class.
How do you make a public variable in Visual Basic?
To make a variable accessible from any code that can see it
- For a member variable, place the Dim statement for the variable inside a module, class, or structure, but outside any procedure.
- Include the Public keyword in the Dim statement.
