Answer:
Polymorphism
Explanation:
You can have a basic button class that gets inherited by other classes.
class Button {
function pushButton(){}
}
class ElevatorButton extends Button{};
class BigRedButton extends Button{};
With these new classes, they inherit from the basic button class. They can decide what happens when the method pushButton() is called.
You don't need to worry about what pushButton() actually does, you can just call it if the object is of the type "Button" and you can expect it to work.

Following are the program definition in the Java Programming Language.
//define a class
public class Clock
{
//set integer type variable and initialize value
private int hours=12;
//set boolean type variable and initialize value
private boolean isTicking=true;
//set integer type variable and initialize value
private Integer diff=5;
}

Following are the description of Code.
- Firstly define a class "Clock" with the "private" access modifier.
- Then, set the integer data type variable "hours" with the "private" access modifier and assign value 12 in that class.

- Finally set Integer class variable "diff" with the the private access modifier and assign value 5.
