Answer 1

Fine. But Here, all of my ArrayList elements are
string.
I have to assign all the ArrayList elements into the
the array.
Is it possible. give the sample code.Yes say your array list has all string elements here is how you do it...
ArrayList<String> alist = new ArrayList<String>();
alist.add("1");
alist.add("2");
alist.add("3");
alist.add("4");
alist.add("5");
String arrayStrings[] = alist.toArray(new String[alist.size()]);
NOTE: Works with J2SE 5.0 or above
and for 5.0 below the below could be a solution.
public static void main(String[] args){
Test test = new Test();
// Syntatically incorrect
String[] s1 = new String(lst.size());
// Would get a Type Cast Exception as ArrayList.toArray() returns Object[] not String[]
s1 =lst.toArray();
// and btb what test.toArray() do ??
//s1 = test.toArray();
}you may have to restructure it to
public static void main(String[] args)
  Test test = new Test();
   int size = lst.size();
   String ArrayString[] = new String[size];
   Object k[] = list.toArray();
   for(int i=0 ; i < size; i++)
     ArrayString[i] = (String)k;
Hope that might be the one...
