Why we use getters and setters in Java instead of public variables?

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 do we use get and set methods in Java?

The fields of a class can be made read-only (by only providing the getter) or write-only (by only providing the setter). This gives the class a total control of who gets to access/modify its fields. 2. The users of a class do not need to know how the class actually stores the data.
