hi, I need to do random addition and deletion from array and will store pointers in the array. Now I am using RPointerArray for the purpose. Is there any method to re-arrange array index after deletion an item from the array. let's say I have 4 items in the array ( 0,1,2,3) now item 2 is deleted from the array ( 0,1,3). Is there any method to rearrange array index to (0,1,2) .Or is there any other data structure suitable for the purpose? Thanks
