Java is not pure Object Oriented:
because it supports primitive data types (like: int a;), we can write pure Object Oriented with the help of wrapper classes (using new keyword like: "Integer a = new Integer ();").

Main difference of collection and collections sir...?
Collection is a parent interface in collection framework and Collections is a utility class
Why we are not write any method in abstract class
We can write method definition in abstract class and we can make method as abstract which definition will be provided by its child class
No questions on collections and strings.. could have covered on that..
Yes sure
what is super keyword in java
i want multithread and collections interview questions
It's available chec next videos
Really helpful sir
Sir pdf provide kijiye
We don't have PDF
any way we cannot create object form abstract class and intrface but abstract class contains constroucter but interface do not why? please tell me
Abstract class means to be extended by concrete class and in Abstract class Abstract method and normal method both can resides along with class variables, so to initialize these instances variable wherever child class using these Abstract class we require constructor to initialize abstract class variable before child class constructor while creating an object of child class.
But in interface by default every variable is static and final and once it initializes we can't change it, so interface doesn't have constructor. Because when we try to change it through constructor we get runtime error.
Really helpful keep it up but I have a question can u please tell me overriding concept why we are creating the same name object in parent class and child class is that required because I can create seperate method in class as creating in all the child class my question is why same name of method is created in parent class ... Hope uu get my question ❓ m soo confused revert back if you can thanks
When we are not satisfied with parents class method then we can override this function in child class and can give our own definitions.
Sir please make videos on advanced java
Yes will do. Stay connected
bro only jdbc comes under advance java
Good ❤
Thanks
Please upload program also
Ok we can try in next videos
ما هي اول لغة اتقنتها؟؟
First we have to learn about c programming then c++. After this you can start learning any Programming language
Can have chances to ask intervier question about the collection or threads topic
Multithreading is already shared we will share about the collections soon
How to code in java

How customer use JRE????
While software installation we can simply install jre no need to jdk
Sir only learning java do not learning other language so scope java in feature sir please reply
Others have also scope. Many frameworks are there who are dependent on java.os Java is also having huge scope
Sir what is difference between public static void main and static public void main.
I was asked this question in my interview
There is no difference. Both are same work.
No difference. We can declare access modifiers any order. But java recommends public static void main
