These are the most common nd Basic part of java
But people are confusing about it. Nd u explained it very Simply way. Thanks Naveen 😊

15:00 It's because of the "final" keyword.
If X was only static and not final, the static block would be called.

Explaination in a layman's terms would be, if a variable is static and final, it means that it's shared between all objects and it's value cannot change, hence the compiler will simply put it's value in the calling statement instead of referencing it from the original class.
If it was not final, means the value of x is changeable, therefore directly putting the value in the calling statement could cause inconsistencies.

11:49- the question is run program without writing main method but you executed program inside the main method by creating object.

[AdamantMindset]

Okay this is the first time I heard of such things..

[m.smanoj]

Awesome questions my friend 🤗.even in clg they won't teach this hidden techniques

[SumitSharma-qqhk]

Awesome.... Everytime there is a video by you, I learn something new

[munich-germanylife]

Overall explanation was good but I didn't find the answer for below things :
1. If Constructor is Private and I am writting a object creation in static block how I can use it outside class
2. Can I run the code witout Main() method, of yes I think you could have given one example in one class without main method instead of calling a second class where main method is not there
But again sir big fan, always love your content.Please keep on doing your good works and help others to upskill there knowledge

[vibhanidhi]

Thanks Naveen..👍👍it's really helpful..pls continue such type of interview questions series

[ahamedabdulrahman]

Naveen, a great series. One doubt. In question 4, the question is to run a Java program without main() method. You have created a class without main method but called that class from another main method only, isn't it?

[saikigaj]

Perfect series for interview preparation...👌

coming to my question,
Sir may you please tell me the practical application of the static block and the instance Inisialisation block in a real world situation. An example describing both of these applications would help me a lot.

[arunprasath]

Hi Naveen, i am curious to understand where exactly a static block can be used in a framework design and how it will serve the purpose. Also a request when you explain the concept please explain where exactly it will fit in framework. It will help us to create better framework.

[palspal]
