Answer / mike
collection(lowercase c)represents any of the data
structures in which object are stored and iterated over.
Collection(Uppercase C)represents the interface which is
extended by three other interfaces(Set,List and Queue,Map
doesnt extend Collection interface).Guys,its extended not
implemented(hope you all know the difference between the
two,interface can extend interface,remember?)
Collections(upper case C with s at the end)this the
java.util.Collections class that holds a pile of static
methods for use with collections.
