Instantiating Object (Java) [duplicate]

This question already has an answer here:

• Is it possible in java to create 'blank' instance of class without no-arg constructor using reflection? 6 answers

I'd be very grateful if someone helped me with this problem. There is a Class A in which everything is private(fields, constructors, methods). My task is to instantiate an object from Class A and then invoke the methods it has. I have a restriction not to change anyting in Class A.
