defining 2 public classes in single java file error

Question

I try to define two classes with public access modifier. But i got an error that the classes should be defined in respective java files.

my question is Why cant we have two public classes in one java class file?

i understood the error i just want to know , why cant we do it ? i mean the reason behind it

Thanks

Because that is how Java has been defined. If it did allow two public classes and both had main methods, which would be *the* main method? — Hovercraft Full Of Eels, Nov 22 '13 at 04:32
Here is a link that explains it well IMO http://stackoverflow.com/questions/3578490/why-only-1-public-class-in-java-file?rq=1 — Josh Engelsma, Nov 22 '13 at 04:36
we can have 2 public class in one file if the second class is a inner class `public class test1 { public class tes2 { ... } }` — SpringLearner, Nov 22 '13 at 04:42

I think this could explain why in a very simple way:

Because if you did, the name of the java file wouldn't be the same as the class name.

However, be sure to understand that is valid:

public Car{
 public Motor{

 }
}

Here you can read more about it.

You can read more about it in this interesting oracle forum discussion.

Hope it helps.
