Is constructor overloading possible if yes then explain and if no then why?

It is never possible . Constructor Overriding is never possible in Java. This is because, Constructor looks like a method but name should be as class name and no return value.

Constructors can be overloaded in a similar way as function overloading. Overloaded constructors have the same name (name of the class) but the different number of arguments.
