Fetching an ArrayList

If suppose I add an object in ArrayList :
Ex : If Obj is my object having variables an int, string and String[].

Obj ob = new Obj(1,"xyz", str[]);
List list = new ArrayList();
list.add(ob);

Now while fetching back the contents of arrayList I'm getting str[] as a second element , where it has to be part of first element.

String[] results;
results = (String[]) list.get(1);

results[1] --> 1,"xyz"
results[2] --> str[]

How do I avoid this? So that I get results[1] --> 1,"xyz",str[]

ArrayList contains the reference of the object.
Now if you fetch the contents of the ArrayList you'd get object reference. There's no second or third element. Just invoke getter method on the reference and you'd get the value.

Here you are adding Obj into list [only one element is there]

String[] results;
results = (String[]) list.get(1);

you are trying to get 2nd element of list upon that your are casting Object to String !

good practice to be introduce generic here

Thanks a lot for reply....
Do you mean I'm trying to add only one element and trying to get second one? If Yes then that was a typing mistake...sorry

I just want to clarify that arraylist get the elements the way they were being added irrespective of casting...

Correct

You can't cast Obj to String[]. Have you ever tried to compile your code? Where did you take those results from?
