Why are there two files, Cow.java and Main.java?

I don't understand how these two files run at the same time. When Main.java is called, how does it access Cow.java? Why cant they simply combined into one file?

How would somebody run these two files on an IDE like Eclipse?

Ben Deitch , are you out there?

Hi Bob, He complies and runs the Class called main.java but does not type in the cow class in directly the cow class is complied too as part of the whole program. It does this beacuse main has a method called:

public static void main(String arg[])

This is a entry point for java programs, when the complier hits the method it says to itself okay what do it need to do now, so looks in that method for things to execute. In this case it initialises a Cow object by Seeing 

Cow cow  = new Cow("larry")

so it jumps to the Cow class and pulls in a cow object. To which it goes to the next action in the 

public static void main(String arg[])

Which is to finally print the message out.

Hope this Helps a little Michael

That helps a TON, I did not know how the main method worked. Thanks for taking the time Michael!
