Why constructor is declared with different modfiers? I know that constructors are not inherited and what is the use to declare with diff. modifiers?

A private constructor prevents the class from being instantiated (see the Math class). A class with protected constructors could only be instantiated by a child of that class or by a class within the same package as that class.
jls:


A protected constructor of an object may be accessed from outside the package in which it is declared only by code that is responsible for the implementation of that object.

Thanks Paul, but most of the constructors are public(to be accessed anywhere) or default(to be accessed in the same package). Isn't?
