Can we get Arraylist from String.Please check the code

Question

Hi all,
I have just pasted my code over here.Can anyone of you find the solution for obtaining the Array list from the String.
For Example :
ArrayList al = new ArrayList();
al.add(new byte[2]);
al.add("2");
String stringVar = "" + (ArrayList) al;
Here I can convert the arraylist into string.But can we do he vice versa like obtaining the above arraylist from the string?If please advice me.
URGENT!!!!

cudIf you run the code you posted you will observe that the string form of the list does not contain all the information of the list: in particular the array elements are missing. It follows that the "vice versa" conversion you seek is simply not possible.
A variation on this theme is the following:import java.util.ArrayList;
public class ListEg {
    public static void main(String[] args) {
        ArrayList al = new ArrayList();
        al.add("foo");
        al.add("bar, baz");
        String stringVar = "" + (ArrayList) al;     
        System.out.println(stringVar);
}If you think about the output you should be able to conclude that lists with different contents can easily have the same string form.
Just something to chew on.
