What are getter methods and setter methods?
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. Given this, getters and setters are also known as accessors and mutators, respectively.
What is the use of Get and set in Salesforce?
We can touch these two words when we are learning or working on apex controllers. These two are useful to pass the data between VF and controllers. Visualforce requires a “getter” and “setter” to reference a variable in the controller or extension.
What are getters and setters and why are they important?
Getters and setters are methods used to declare or obtain the values of variables, usually private ones. They are important because it allows for a central location that is able to handle data prior to declaring it or returning it to the developer.
What is the benefit of getter and setter methods?
The getter and setter method gives you centralized control of how a certain field is initialized and provided to the client, which makes it much easier to verify and debug. To see which thread is accessing and what values are going out, you can easily place breakpoints or a print statement.

What will happen if getters and setters are made 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 are getters and setters bad?
Getter and setter methods (also known as accessors) are dangerous for the same reason that public fields are dangerous: They provide external access to implementation details. What if you need to change the accessed field's type? You also have to change the accessor's return type.
Why do you need to use getters and setters in encapsulation?
Getters and Setters play an important role in retrieving and updating the value of a variable outside the encapsulating class. A setter updates the value of a variable, while a getter reads the value of a variable.
Why getters and setters are not public variables?
getters and setter can have validation in them, fields can't. using getter you can get subclass of wanted class. getters and setters are polymorphic, fields aren't. debugging can be much simpler, because breakpoint can be placed inside one method not near many references of that given field.
Should getters and setters be public?
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.
