getter and setter In java

private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}In MyEclipse, you can just generate setter and getter by:
choose the parameter defined -> source -> generate getter and setter

The getter and setter methods can help hide internal state and requiring all interaction to be performed
through an object's methods is known as data
encapsulation — a fundamental principle of object-oriented programming.

In fact:

Your object uses setter to:

restrict and validate data passed to the setter

hide its inner data structure (other object are interested by a service not how the service is built, this can also include optimisation)

preserve its integrity in every state (changing other fields if required)

it will use getter to

format data in output as desired by the client

control a sequence of services (for instance it will provide data if and only if a connection has been established)
