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])
}
}
}
