Reports instantiation of generic classes in which the <> symbol (diamond) is used instead of type parameters.

The quick-fix replaces <> (diamond) with explicit type parameters.

Example:

List <String> list = new ArrayList<>()

After the quick-fix is applied:

List <String> list = new ArrayList<String>()

Diamond operation appeared in Java 7. This inspection can help to downgrade for backward compatibility with earlier Java versions.
