In my current project I'm trying to instantiate new objects based on a Class object, for example:

1. import java.lang.reflect.*;
2. void setup(){
3.   Class cls = SomeClass.class;
4.   Class[] argType = {int.class};
5.   try{
6.     Constructor ctor = cls.getConstructor(argType);
7.     SomeClass instance = (SomeClass)ctor.newInstance(3);
8.   }
9.   catch(NoSuchMethodException e){
10.     println(e.getMessage());
11.   }
12. }
13. class SomeClass{
14.   int x;
15.   SomeClass(int x_){
16.     x = x_;
17.   }
18. }

I run into an InstantiationException on line 7.  Before adding the try/catch blocks I also had a NoSuchMethodException on line 6.  This is my first time working with reflection so I'm sorry if the answer is obvious, but any clues on why this happens/how to fix it are greatly appreciated!


EDIT:  I think I've got it!  Looked around at a few threads and played around with different tabs/names.  Now the only trouble is using methods in other classes to draw in the main class.  At the moment I'm trying to use a PGraphics object to do so, is there a better way?
