What is the need for using Constructor?Can'twe just initialize a data member in a method?

Question

Does Constructors have any special significance?Pls explain in simple language.?(IN JAVA)

Answer 1

Constructor just serves to makes operations (like setting a atributte) or call a method when a object is created .

It's not obrigatory to use it but for readability you can leaves empty.

But normally you can always set your attributes (if you have some value to set) with a standart value. It's a good practice.

Answer 2

Wouldn't that make things unnecessarily difficult?

You would need to instanciate the 'empty' object, then 'fill it up' afterwards.

With a constructor you can initialize the object in a single line.
