Program:
import java.util.*;
class IteratorDemo{
public static void main(String args[]){
ArrayList al=new ArrayList();
System.out.println(“Initial Size : ” + al.size());
al.add(“C”);
al.add(“A”);
al.add(“E”);
al.add(“B”);
al.add(“D”);
al.add(“F”);
System.out.println(“Original Contents of al : “);
Iterator itr=al.iterator();
while(itr.hasNext()){
Object element=itr.next();
System.out.print(element + ” “);
}
System.out.println();
ListIterator litr=al.listIterator();
while(litr.hasNext()){
Object element=litr.next();
litr.set(element + “+”);
}
System.out.println(“Modified Contents of a1 : “);
itr=al.iterator();
while(itr.hasNext()){
Object element=itr.next();
System.out.print(element + ” “);
}
System.out.println();
//Display the list backwards
while(litr.hasPrevious()){
Object element=litr.previous();
System.out.print(element + ” “);
}
System.out.println();
}
}
Result:
Initial Size : 0
Original Contents of al :
C A E B D F
Modified Contents of a1 :
C+ A+ E+ B+ D+ F+
F+ D+ B+ E+ A+ C+
