correct way to instantiate bunch of classes at once

I have a class Main.java in which I need to instantiate a bunch of other classes say C1.java ... C50.java. I am not able to think of an elegant way to instantiate these 50 classes in Main class. If I simply put all instantiating code in one place it looks so crowded and ugly. Today I have 50 classes to instantiate, tomorrow this count can increase to 100, then this situation will get worse. Can you please suggest an elegant way of instantiating all these classes without making Main class crowded with instantiation code. I am not aware of any design pattern to do this.

I am thinking to create an array of classes that needs to be instantiated and use reflection to instantiate them.
