im a little stuck, i have a mutable map with Names as a key and address's as a value, is it possible to "get" the key and value at any given index. For example, if i wanted to know the 6th in the map

Usually maps do not specify an order, and if they do (e.g.

LinkedHashMap

) access to the n-th element is usually quite slow. This is probably not a good idea to do 😉

LinkedHashMap’s get is O(1) so that’s not an issue thankfully!

get

is, yes. But "find me the 6th element" is O(n)

Ah yes, you’re right

But that performance does not even matter, unless your map is quite big. I just think it's a bit of a code smell.

@mcscruff Maybe you would be better off with a class containing a name and an address, and then store them in a list?

im actually looking at a class now, just working out how to use it correctly
