55 Java Superclass Subclass Typecasting |

"Learn How To Design + Code A Complete App From Scratch To Playstore"
-~-~~-~~~-~~-~-

This Java tutorial video talks about typecasting between superclass and subclass objects in Java, A superclass reference variable can refer to subclass objects, however the reverse requires explicit cast operator to typecast. It may throw a ClassCastException if the typecasting is attempted between incompatible objects.

I was struggling to understand polymorphic casting until i find this vídeo! Very effective and simple explanation! Congrats and thanks a lot for your Help! Just loved it!

I like how you explain what you are teaching. The best I've seen so far. Here's a question - in creating Person p2=new Student(), how is the reference variable p2 any different then s2 in creating Student s2=new Student()? Won't they both be able to refer to all the variables in the Student Object the same way? If true, then what would be the purpose of creating p2 of Person type to refer to a Student Object?

These slides teach you everything you need to get started with Java programming. I will be adding a PART 3 in addition to the two parts that will cover more complex topics. I was so excited with these that I couldn't wait to upload it ASAP!

I struggle to understand that concept of Person p = new Student() when he says at 05:15 that object p has five available fields - name, age, address, marks and rollNumber because still when we try to use p.marks or p.rollNumber - compiler shows error. So what actually means that Person p = new Student() has five fields available?

[amankul-yt]

Hi Vivz, @9:20 you said P2(=new student) has a student object inside it and hence can be used for typecasting.However I saw that even reference variable p (which = new Person) can be used for the same.Am I correct ? Great videos btw.

Why can't I watch your java course on Coursetro? It says: the video can't be loaded because the format is not supported or the network faild! I tried from different device but the same problem! Please fix it as soon as possible! Thanks
