Core Java Interview Question on Inheritance | Automation Testing interview preparation by MKT

No

no

No

Yes... We can inherit the properties of sub class in to super class by up casting in this up casting child class will hide. Then we have to do the downcasting in the expliste way... Then we can access the sub class properties to the super class. With out doing up casting we are not able to do the downcasting.

No, only a child can inherit not a parent inheriting from a child.

Yes

No, it is not possible.

Yes, super class can inherit the properties of sub class

Yes, super class inherit the properties for ad ub class

Yes by upcasting concept

Yes by getter and setter method

Imposible, in POO the super class is just static and the child class can take the super class prop to modify and change it.

Yes,we can call

No it is not possible superclass inherit the property of subclass but we can do it forcefully by downcasting.

Course details plz

By using of extends we can get properties from super class to sub class.

No

Downcasting explicitly

Yes we can, by using Up-Casting

Super class can't inherit the properties of child class. But we can create an object of a child class with the reference of the parent class....

We can do it with help of “super” keyword to share properties of child or parent or either between them.

No, under normal circumstances, it is not possible to inherit a superclass into a subclass. Inheritance is a fundamental principle of object-oriented programming where a subclass can inherit properties and behaviors from a superclass

Yes, explicitly

class Animal{
void eat(){
System.out.println("This animal can eat");
} }
class Bird extends Animal{
void fly(){
System.out.println("This animal can fly");
} }
class Program{
public static void main(String args[]){
Animal a=new Bird();
((Bird)a).fly();
} }

By upcasting

No, the Vice versa is possible because whenever any class inherits the property of any class then it's always termed as child class not super class.

by using this keyword??

S

No

No

No it's not possible

In object-oriented programming, it is not possible for a superclass to inherit the properties of a subclass. inheritance is a one-way relationship, with subclasses inheriting from superclasses, not the other way around.

Downcasting

Yes when we write
Webdriver driver=new chromedriver()

No

No, in object-oriented programming, inheritance works in the opposite direction. A subclass (child class) can inherit properties and methods from a superclass (parent class), but a superclass cannot inherit properties defined in its subclasses. Inheritance allows subclasses to extend or specialize the behavior of the superclass.

Yes it is possible with upcasting we can convert child class objects to look like parent class object and access the properties of child class with help of parent class objects.
