Please Help me on recreating deleted arrays

Question

Hi,
I'm trying to recreate a deleted array as follows:
array=null;
Array array[] = new Array[100];
addToArray("elem1","elem2","elem3");
but doesn't work. I'm unable to recreate/populate the array. Can someone please help me with this?
I declared the array null first because the array was previously existing.
What I need to do is to be able to add array elements dynamically and delete some at the same time.
Deleting some elements seemed to be a complicated process so I thought of deleting the entire array instead then just recreate it and populate with required elements. I should keep the same array name.
Thanks!
Anna

Answer 1

array=null;
Array array[] = new Array[100]; // on this line you declare the variable array once again : the compiler doesn't accept it.
addToArray("elem1","elem2","elem3");
What I need to do is to be able to add array elements
dynamically and delete some at the same time. You can also give a look at the Collection
http://java.sun.com/docs/books/tutorial/collections/implementations/general.html
and especially the class "ArrayList" http://java.sun.com/products/jdk/1.2/docs/api/java/util/ArrayList.html
This class provides methods to add, delete element and dynamically enlarge the array.
Good luck
