public @interface ProgramClass

This is the marker annotation for a "Main" class. That is a class that has a method

public static final void main( String... )

and is meant either as the starting point of a larger application or as a standalone program.

Particular the latter will have often just static methods – like utility classes – and therefore causes warnings in some tools. This annotation allows to suppress these warnings.
