Clear Java Cache

I want to know how you can clear your Java Cache using Java Code or CMD Line code.

This should be done on a Microsoft Windows computer anywhere, starting with Windows 7 and above.

This must be done on multiple computers so that the file paths are different.

The application uses Javaw as the default application with which it starts (not to be confused with Javaws or Webstart - I already have code to clear the Javaws cache). So I need to know how to clear the Javaw cache.

Given the context in which this question was originally asked, I suspect that the OP actually (was) actually asks about caching Java Webstart applications, but does not understand that this functionality is part of Java Webstart, and not Java SE as a whole.
