Hi,

I'm wondering what is the difference between

Map m = new Treemap()

and

Treemap m = new TreeMap()?

    Here Map is an interface where as TreeMap is a class which implements Map interface. TreeMap is a Red-Black Tree based Map implementation. The TreeMap is sorted based on the natural ordering of its keys or by a Comparator provided in the constructor.
