Hi Friend,

Try the following code:

import java.util.*;

public class DisplayCommonElement{
public static void main(String[]args){
ArrayList a1 = new ArrayList();
ArrayList a2 = new ArrayList();

a1.add("a");
a1.add("b");
a1.add("c");
a1.add("d");
a1.add("e");

a2.add("a");
a2.add("b");
a2.add("c");


int array1Size = a1.size();
int array2Size = a2.size();

if (a1.size() > a2.size())
{
int k = 0;
for (int i = 0; i < a2.size(); i++)
{
if (((String)a1.get(i)).equals((String)a2.get(i)))
{
System.out.println((String)a2.get(i));
}
k = i;
}
}
else
{
int k = 0;
for (int i = 0; i < a1.size(); i++)
{
if (((String)a1.get(i)).equals((String)a2.get(i)))
{
System.out.println((String)a2.get(i));
}
k = i;
}
}
}
}

Thanks
