Hi, I'm trying to implement this basic graph but keep running into the syntax error "Cannot instantiate the type CollectionInteger", wondering how to fix so I can get it working with the collection, thanks.
#Cannot instantiate the type CollectionInteger

Collection is an interface
you cannot instantiate an interface without implementing its methods
jagged blaze
you have to provide array too and as @oak harness said, Collection is an interface
oak harness
But you can use an ArrayList or any class that implements Collections instead
