We get it from encapsulation, the getter method is used to get the value of private members and setter method is used to set the data of private members

[sravschinna]

Getter and setter methods are the topic from Encapsulation

[srivignesh]

Encapsulation. They help in achieving data binding i.e., not exposing the variables of the class (by privatising them) and accessing them strictly via these methods for other classes to use

[nagavenigowda]

Hiding the data binding the method to hide the internal implementation, To achive getters and setter methods internally

[b.mallikarjunamalli]

Getters and setters methods are in encapsulation in java

[alizaimam]

Getter and setter are used in Encapsulation

[Gabriel-xqtn]

I will say just for OOP. Because to implement a get or set method you just don't need an abstract class. Any class can implement a get or set method as long as it has field or fields. Get and set are considered as special methods for returning and updating field values.

[survivorinsan]

Encapsulation…. Binding method with its properties

[rockycreation]

Getter and setter methods are the Topic of Encapsulation

[carefulcook]

By using getter and setter method we have to access the data which is in private of the class itself

[sushmakshirsagar]

It is used for access private variables outsides the class

[Itsme_Saku]

Getter and setter methods are the topics from 'Encapsulation' in java

[priyankachitte]

Getter and setter are used in "Encapsulation"..

[Decoding]

Encapsulation where we make private data member and public classses to use getter and setter

[Gabriel-xqtn]

Abstraction
Does an abstract class have fields?
An abstract class has an abstract.
An abstract class cannot instantiate an object. Hiding unnecessary data from the clients code ( encapsulation).
method without a body. Meaning the implementation is for the child class.
Get and set method is a general concept for returning and updating fields value in OOP of a class. Either a simple class, inheritance, polymorphism, abstraction etc.

[deepakkamble]

Getter and Sette are two method from Incapsulation
