Java 10 is likely to add support for `List` but for now you need `List` — Peter Lawrey, Sep 11 '16 at 08:37

You can't use int as the type parameter for List, it has to be an object type. So you need List<Integer>.

You tried to declare a generic List using a primitive int as the type. This won't work, because only class types which extend Object are allowed. This is the code which achieves what you were trying to do:

private List<Integer> Lpaths;
