I know it is not a good coding practice to declare a method as private in an abstract class. Even though we cannot create an instance of an abstract class, why is the private access modifier available within an abstract class, and what is the scope of it within an abstract class? In which scenario is the private access specifier used in an abstract class?
check out this code where Vehicle class is abstract and Car extends Vehicle.
package com.vehicle;
abstract class Vehicle {
// What is the scope of the private access modifier within an abstract class, even though method below cannot be accessed??
private void onLights(){
System.out.println("Switch on Lights");
}
public void startEngine(){
System.out.println("Start Engine");
}
}
Within is the same package creating a Car class
package com.vehicle;
/*
* Car class extends the abstract class Vehicle
*/
public class Car extends Vehicle {
public static void main(String args[]){
Car c = new Car();
c.startEngine();
// Only startEngine() can be accessed
}
}
