What packages in java?
A package is a namespace that organizes a set of
related classes and interfaces. Conceptually you
can think of packages as being similar to
different folders on your computer. You might
keep HTML pages in one folder, images in
another, and scripts or applications in yet
another. Because software written in the Java
programming language can be composed of
hundreds or thousands of individual classes, it
makes sense to keep things organized by placing
related classes and interfaces into packages.
