"Create, manage and
run configurations" dialog.
There are various dialogs with that title.
Are you speaking about Debug, Run or External Tools?
If you want to run a Java class, you should use Run. The simplest way to
run a program without creating a configuration by hand is right-clicking
on the class name (e.g. in Package Explorer or Outline) and select Run:
the configuration is created by Eclipse and you can modify it later.
