Can we write initialization code in servlet constructor

Hi all

I have a doubt regarding the constructor in servlet

I have learnt that we can write a no-arg constructor in servlet and this costructor is called by the container.
I want to know that can we write servlet initialization code in this constructor instead of writing it init() method.

Thanks

You should never use a constructor in a servlet; it's bad practice. All required initialization should happen in the init method.

Servlet initialization code belongs in the init() method not in the constructor.

I agree that its a bad practice to write a constructor in servlet class.
My question is still not answered, Is it legal or is it possible to write initialization code in servlet constructor.

It is not illegal in the sense that the judicial system of whatever jurisdiction you're in will come after you if you do it.

As to whether it's possible, how have you tried to prove or disprove it?

Ask yourself: in a constructor how will you access important information like the ServletConfig instance?

Got it..
Thank you all
