Im doing a project about a leisure centre and where the members have ids, they have gates that add or deny them permssion, when they are granted access, their location (zone) gets updated, so if a user is moving from the siwmming pool (zone2) to the sauna (zone3) then the zone value changes.
I want to be able to make a non-fixed 2D array that needs to store the following. Im using bluej ide if that makes a difference.
Idnumber------Zone
101----------------1
102----------------1
103----------------3
I need to be able to update the zone value how do u do this also. So it says something like find idnumber 101 and change the value next to it
please paste code if u know how to do it
