Hi friend,

Code to solve the problem :

import java.util.*;
class ArrayListToString
{
public static void main(String[] args)
{
ArrayList al = new ArrayList();
al.add("a");
al.add("b");
al.add("value");
al.add("c");
al.add("d");
al.add("value");
Iterator itr = al.iterator();
String strVal="";
while(itr.hasNext())
{
strVal+= itr.next().toString()+",";

}

int lastIndex = strVal.lastIndexOf(",");
strVal = strVal.substring(0,lastIndex);
System.out.println("Output String is : " + strVal);
String strAr[] = strVal.split("value");

for(int i=0;i<strAr.length;i++)
{
System.out.println("strAr["+i+"] "+ strAr[i]);
}
}
}


Thanks
