The type Set is not generic; it cannot be parameterized with arguments <Integer>

Question

I am facing this weird problem with my Eclipse. Getting this error

The type Set is not generic; it cannot be parameterized with arguments <Integer>

I cleaned and build my project again. Checked my Configure Build path and ensured that JRESystemLibrary is above MavenDependencies in Order and Export.

Googled as well but I can't find any issue with my code. Why is the error popping up.

Answer 1

When you call Set it is being taken as your class Set, not java.util.Set.

Change the declaration to java.util.Set and it should be resolved.

Answer 2

Your main method thinks Set is the class that it's contained in.

You want java.util.Set

My suggestion would be to rename your class :p
