Storing Data

[Khorod]

Goodday everyone,

About 3 weeks ago i have started picking up java, and trying to grasp the basics i decided to try and put together a simple yet challenging program.

the program basicly needs to store multiple names and a value that goes with each name to a file, after which i want to be able to edit and change the value.

Now my question is what would be the best way to realise this (keep in mind i might want to display the entire list in a GUI) i was thinking of having an array go through the file each time you want to change a value by searching for the name that the user inputs, however this seems rather difficult in terms of flexibility, i also noticed the Linkedlist in the API, at first glance however it seems this only stores 1 variable (be it string or int) and not 2?

Could someone give me a push in the right direction?

Thanks in advance, Khorod.

A fascinating question because there are so many possibilities.
Some suggestions:
A List (LinkedList, ArrayList, etc) can take any kind of object including another List, an array (or multi-dimensional array) or a custom class object.
A "Data Store" class can have any thing you want in it along with methods such as write or draw.
For instance:

class PseudoStore {
    String name;
    int id;

    public PseudoStore(String name, int id) {
        this.name = name;
        this.id = id;
    }

    public String toString() {
        return "PseudoStore[name:" + name + ", id:" + id + "]";
    }
}

Then you could do

// For generics (j2se 1.5+)
List<PseudoStore> list = new ArrayList<PseudoStore>();
// or, for non-generics
List list = new ArrayList();
list.add(new PseudoStore("John Hancock", 22));
...
String name = ((PseudoStore)list.get(0)).name;
...
for(int j = 0; j < list.size(); j++) {
    PseudoStore store = (PseudoStore)list.get(j);
    System.out.println("store("+j+") = " + store);
}
