Hello, in this Java programming video, we are going to take a look at the map collection. And the map collection is used to store data, multiple pieces of data, but link it with a unique key and instead of just being like 0123, you can do that as well if you want to do that wrong with that, but you can, you know, make it a bit more unique. Our it's gonna be a bit more specific, like strength for example. So first of all, we'll do it in Java. Asterix I'm going to do map, no color mapping, because the hash map like so. And now what we're going to do is add some data to a mapping or we add an element.

And first of all, we specify the key from the call it Key one now, value one and I'll just duplicate this why not hug I'll push them okay? system quintella. nappy There we go. We've printed in more than the key along with the value as well. So the, the order can, cannot be guaranteed but you just access it, why you know, a particular key, so we can just do some filming To print out a particular system, print line, we can do not get into the variety of of the methods, I will provide a link as usual so you can see all of the different pieces of functionality to do with maps. So don't get cheerful commodity of teen printer.

We get that but you want to access a particular one and you know which one you want to do it. If you have any questions, feel free to reach out and I look forward to seeing you in the next awesome video.
