Arrays

[Sharoo]

Hi everyone,
I was wondering if someone could give me a hand with my problem.
So I have set up an array that has 20 positions available in it (0 - 19) and I have initialised values in the first five positions (0 - 4). Now my issue is that when I use a scanner to input data into a field it replaces the data I already have there. I think I would need to use a while or if statement and search for a "null" position and then place the new data there, but I'm not 100% sure.
Any help would be greatly appreciated.

You could do that, but using a List of some form (ArrayList or LinkedList) would be easier.

kind regards,

Could you please enlighten me on this List method, I don't think I have ever used one before I'm still only a Java beginner.

An ArrayList (or LinkedList) is like an array but it grows when you add a new element to it so you don't have to keep track of it; read its API documentation for the gory details.

Thank you so much :)
It sounds like a list is the way to go.
