Java interview shorts 14 - Liskov substitution principle | polymorphism in Java #javainterview

in this video we will discuss about liskov substitution principle from SOLID. we will see a polymorphism example and will expirience how it is connected to Liskov substitution principle.

Parent class reference can hold the child class object.
It applies to interface, abstract class and it is also polymorphism

[ramabookstroremalang]

looks like formal logic: realization of genus to species. this is the reason why I really love JAVA.

[VishnuVijai_]

So dynamic method dispatch is called liskov sub?

[Gautam_Mandaliya]

As per my knowledge, It is a concept of Inheritance
Here Animal class is Superclass/Parent class and Monkey is Subclass/Child class, so basically it is upcasting we are performing here. Conversion of subclass type into superclass type as Upcasting or Implicit Type casting

[santhoshchandran]

@seleniumexpress can u give ur answer here with brief explanation?

[nellainayagam]

Method over riding Run time /dynamic polymorphism

[sudheerbommisetti]

After achieving inheritance only- we can able to create the object like that.
So I think the answer is inheritance.

[lathasrikoyya]

It is having has-A relationship, so the answer is inheritance

[mohamedasifar]

Run time polymorphism many say its inheritance but with inheritance only we can achieve run time polymorphism

Why?

Because first compiler check if there is animal class and monkey class are fefined if its class file will be created next in runtime monekey object will be created and assigned address to animal variable so it is run time time polymorphism

[amitbhagat]

You have already given answer in title 😅

[HR-pzts]

Poly- many ways to represent the same thing

[kunalkakkar]

Upcasting, we do this to achieve abstraction 😁.

[movietrailer]

Monkey class is extending Animal class without that you can not create object as Animal A= new Monkey() so answer should be Inheritance but most comments are indicating Polymorphism can anyone explain why polymorphism?

[abhilashpatel]

This is not Liskov principle. This is just polymorphism.
