why not public?

Posted: Mar 22, 2005 10:04 PM

package java.net;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.InterruptedIOException;
import java.io.FileDescriptor;
import java.io.ByteArrayOutputStream;

import sun.net.ConnectionResetException;

/**
* Default Socket Implementation. This implementation does
* not implement any security checks.
* Note this class should <b>NOT</b> be public.
*
* @author Steven B. Byrne
* @version 1.65, 12/19/03
*/
class PlainSocketImpl extends SocketImpl

...

* Note this class should <b>NOT</b> be public.

Why class above isn't public?

I want the reason.

All classes are "protected" by default, meaning they are visible to all other classes in the same package, but not to classes outside their package.

The designers might want to hide the implementation from the developers.

Again, I did not read carefully.
Sorry
