Packages and static imports in Java

In my previous Java 101 tutorial, you learned how to better organize your code by declaring reference types (also known as classes and interfaces) as members of other reference types and blocks. I also showed you how to use nesting to avoid name conflicts between nested reference types and top-level reference types that share the same name.

Along with nesting, Java uses packages to resolve same-name issues in top-level reference types. Using static imports also simplifies access to the static members in packaged top-level reference types. Static imports will save you keystrokes when accessing these members in your code, but there are a few things to watch out for when you use them. In this tutorial, I will introduce you to using packages and static imports in your Java programs.
