Answer 1

Answer:

a) Print the duplicate elements in the array

Explanation:

I found this code:

This is two for cycle, where we make a comparison among two variables i and j to print duplicate elements.

for (int i=0; i < arr.length-1; i++)

{

for (int j = i+1; j < arr.length; j++)

 {

   if (( arr[i].equals(arr[j])) && (i != j))

       {

         System.out.println(arr[i])

}

}

}
