How to generate "constructor" for parameter object

Question

Hello,
As part of my research project I need to find the "constructor" of a given
parameter object.
For example: Suppose we have the following method -
public void int pop(Stack st) {
//some code...
I want to generate code that calls this method and its parameter with its
constructor. Like -
pop(new Stack(10));
As you can see I need to return a valid instance of the parameter to the
method (null wont do).
I dont know what library or API to use for this purpose.
Your help is highly appreciated.
Thanks,
Fayezin

That's not a great example. If you have a Stack class, then pop() should be a method on that class, not some other class. And if you created a new Stack object, then presumably it would be empty, so popping it should cause an exception.
Anyway, if you want to get the constructor of a class, use Introspection. There may be a better solution though, depending on what you're actually trying to accomplish.
