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!

[diesieben07]

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

[mannodermaus]

Ah yes, you’re right

[diesieben07]

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?

[mcscruff]

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

[mcscruff]

i got it working, a class is a much better way to do it.
