Hello,

I know Collections is a utility class in java.

Are there any comprehensive list of all utility classes like Collections? Is Iterator is a utility class too?

thanks

No, Iterator is not a utility class. It is not a class at all, but an interface.
I have never seen a list of utility classes. Would you like to write one?

No, but the general pattern is that their names are the same as some fairly basic type (like Collection) with an "s" added on the end. Have a look at the list that Bear gave you and see if you can find some.
