public static void main(String[] args)
{
String[] my_array = {"bcd", "abd", "jude", "bcd", "oiu", "gzw", "oiu"};

for (int i = 0; i < my_array.length-1; i++)
{
for (int j = i+1; j < my_array.length; j++)
{
if( (my_array[i].equals(my_array[j])) && (i != j) )
{
System.out.println("Duplicate Element is : "+my_array[j]);
