It is a Collection of items ( a custom class).The Collection is just declared as a Colection.

What's a name of an object? You are pretty vague? Why can't you be more specific?

Create a map

Iterate over the collection, get the name of each object, check if it exists in the map. Add it to the map if it doesn't exist, use the name as key and a counter as value. Just increase the counter if it exists.

Ah, nice idea, thanks.Once you have everything in a Map though, how would you iterate through?Thanks!

Get the entry set from the map, iterate over it and print all entries.Kaj
