Hi,
I have a question about HashMaps. If I have a HashMap and I insert an object that has a hashcode of say 10 will the underlying array of HashEntries have 10 elements even though the map contains just one object?

No. The number of buckets is determine by a few conditions. The value of the hashcodes (of the elements) is not one of them.
