Are modules analogous to namespaces in C# or packages in Java?

Java is not (yet) truly modular programming language. Java 8 is 
supposed to include Jigsaw (module system for Java). More about 
it: http://openjdk.java.net/projects/jigsaw/

Packages in D are similar to packages in Java.
Concept of modules as I wrote above, does not yet exist in Java.
