Yes it is possible to inherit properties of Sub-class or Child Class into Super Class by using the concept of Up-casting. Here we create one casting object and by using reference of that casting object we can use Sub-class methods or variables by using Super-class name or reference. Basically this concept is mostly used in Selenium
Example: WebDriver driver = new ChromeDriver ();
where, WebDriver is the Super Interface and ChromeDriver is Sub-class

[akshaysakhare]

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.

[ganeshlondhe]

Yes ....super class inherit properties of subclass by performing down casting. ...we can convert the the address of subclass to Superclass By using that address/reference we can inherite the properties of subclass...!!!

[tanujawaghela]

yes we can assigning sub class properties into super class n it is known as up - casting before perform up casting we supposed to do inheritance operation
down - casting means assigning super class properties into sub class but it is not allowed in java still if we used it then not any compiler error but runtime error should occur

[ramkumara]

In Java, inheritance is a unidirectional relationship where a subclass (also known as a child class) inherits properties and methods from its superclass (parent class), not the other way around. The superclass does not inherit anything from the subclass.

[dasariganesh]

Yes, using we can perform Downcasting casting which has two things should be followed like upcasting valid and downcasting is dine explicitly by user.

[techlearning]

I think No. Inheritance concept is to inherit properties from one class to another but not vice versa. But since parent class reference variable points to sub class objects. So it is possible to access child class properties by parent class object if only the down casting is allowed or possible

[bharathnekkanti]

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.

[shankarguru.d]

yes its possible to inherit the properties from super class to sub class.

[mayurubale]

Child can inherit the property of Parent class .. But In java Parent won't be able to Depend on Child class

[VYRL_Glitch]

Yes, by upcasting which non premative casting. Only inherited priority will be upset from child class to super class.

[murugeshwariravi]

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.

[sahanamotagi]

Yes we can see super class implementation along with sub class implementation by using super keyword, means we can inherit the properties from super class to sub class

[melodiousneha]

This isnt possible using inheritance but it can be possible using method overriding and interface

[kavya]

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

[ashishkumarswain]

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.

[saurabhgabhane]

Yes using dynamic method dispatching we can get super class functionality and that should be public.

[pradeeppatel-yoce]

Yes, it's possible by down casting.

[skkamaluddin]

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.

[yokesh]

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