Can Anyone Explain What is getter and setter with an example ?

Question

It would be nice if the example covers all the things that one should know about getter and setter.

Answer 1

Getters and setters are there for accessing private variables of other classes. For example you have the class "Dog" that has a private object variable String called "name". From the outside you can't change the name like this:

Dog dog = new Dog();
Dog.name = "Fluffy";

It wouldn't compile. Therefor you create Setters and Getters in the Dog class to set and get the Dogs name, without touching the variable directly from the outside. You simply tell a Dog Object to do it itself.

Answer 2

a getter gets somtehing and a setter sets an new value to the variable wich you declared private in your class. so let me give you an example:

public class Test{
private int variable;

public void setVariable(int variable){

this.variable = variable; <- with the this. operator you reference to the private variable
}

public int getVariable{
rerurn variable;
}

}
