Hi,
I hope the answer I am providing is the easiest one among
all others

import java.util.ArrayList;
import java.util.Iterator;

public class ArrayListDemo
{
public static void main(String[] args)
{
ArrayList containsDuplicate = new ArrayList
();

containsDuplicate.add("A");
containsDuplicate.add("B");
containsDuplicate.add("C");
containsDuplicate.add("D");
containsDuplicate.add("A");
containsDuplicate.add("B");
containsDuplicate.add("C");
containsDuplicate.add("A");

ArrayList noDuplicate = new ArrayList
(containsDuplicate);
ArrayList fresh = new ArrayList();

System.out.println("Hello World!!!!!!!!
with duplicates " + containsDuplicate.size());
System.out.println("Hello World!!!!!!!!
with duplicates " + noDuplicate.size());
for(int i =0;i<containsDuplicate.size();i++)
{
String outerObject = (String)
containsDuplicate.get(i);
int count = 0;
for(int j=0;j<noDuplicate.size
();j++)
{
String innerObject =
(String) noDuplicate.get(j);
if(outerObject.equals
(innerObject))
{
if((count == 0))
{
count++;
// fresh.add
(outerObject);
}
else
{

noDuplicate.remove(j);

}
}

}
}

for(int i=0; i< noDuplicate.size();i++)
{
System.out.println("Each
Element :::::::: " + noDuplicate.get(i));
}
}
}
