no we can't have constructor in an interface, why bcz constructor is used to initialize the instance variable stored in an object. Constructor is called concurrently while creating object. We can't create object to interface & also we can't provide instance variable to interface. So we can't use constructor in an interface

Answer / suresh
No a interface should not have constructor,
Because, interface will not extends with object class.
if any class extends with object class then atleast one
constructor should be there, if user fail to keep the
constructor the compiler will keep a default constructor
with first statement as super();.
