In general you should use static imports very sparingly.

One of the few places that they make a lot of sense is in your unit tests:

import static junit.framework.Assert.*;

Static imports were added to Java to stop programmers from implementing the Constant Interface Antipattern.

Link also says: "Used appropriately, static import can make your program more readable, by removing the boilerplate of repetition of class names." – Will Mar 04 '11 at 07:10
Of course they were added because they are sometimes useful, but using them too little will cause much less damage than using them too much. – dbyrne Mar 04 '11 at 07:14
They can do damage? Sounds a little exaggerated. – user unknown Jun 02 '11 at 01:53

It allows you to remove the class name from function calls for static methods, as described with examples in the documentation here: http://download.oracle.com/javase/1.5.0/docs/guide/language/static-import.html
