Why we need constructor inside an abstract class ? || Popular Java interview question

Hi coder!! This tutorial covers a complete abstract class example where we are going to learn why we need a constructor in abstract class.

One of the differences between abstract class and interface in java is :
The interface doesn't have a constructor but the abstract class in Java can have constructor within
it.

Then the question we can’t create an object for
both abstract class and interface then why abstract class can have a constructor when the
the interface doesn’t.

So let's understand this thing with an abstract class program which is a very popular java interview questions .(core java interview questions)

Thanks for the explanation !
But, why cant you initialize all the 6 variables in the abstract constructor though?

[naveenkumarmaddala]

What is the purpose of having variables inside abstract class. This creates the problem in extending classes. Correct me if I am wrong?

[amitsiddhpura]
