[TxMt] Re: Java Compile and run

[David Howden]

Hi Michael,

>From what I remember, all entities in Java are "private" by default.
In the case of classes, this means that you can only access (or "see")
it from code within the package it is contained in.  By running the
helloworld.class file, it will try to call the "main" method on a
class called "helloworld". If the class "helloworld" is not declared
public, it won't be able to see it (hence the "NoClassFoundException"
you were getting).

Cheers,

David.
