I haven't really read that well but...I dont think that i've heard of a similar concept in java courses I've taken.

Could someone explain this concept?

Thanks

Hi

Namespaces are a way to define the classes and other types of information into one hierarchical structure. System is the basic namespace used by every .NET code. Explore the System namespace and you can see that System has lot of other namespace's. For example, System.Io, System.Net, System.Collections, System.Threading, etc.

C# namespace = Java package.
