You should run the class, not the class file. In Java there's no concept of executable files. They are not self contained, they need the JVM to execute them.
| Code: | | m@localhost ~/Desktop/notem $ java EmptyFrame |

Are you sure of it?
Android uses its own API for making window views in application.
Swing is a part of Java Core and used for making desktop applications.
