Question

Hi friends ,
Is it possible to make a newInstance() of a class which doesn't have a default constructor?(java + reflection)

Answer 1

I want to invoke the methods of Math class but it is not possible because the constructor of this class is private!and I cannot make a newInstance even when I use getDeclaredConstructors my code throw this exception :" can not access a member of class java.lang.Math with modifiers "private" ".what can I do to solve this problem?

Answer 2

You cannot create an instance of Math because it has no constructors, default or otherwise, it consists of only methods. Basically it is a collection of function calls and not a collection of "types" that define a larger object.
