Enter an integer: 3
Enter an integer: 2
Enter an integer: 1
Enter an integer: 5
Enter an integer: 4
Enter an integer: 5
Enter an integer: 2
Enter an integer: 4
Enter an integer: 5

use Set to display distinct values. I guess you want to display them in the order they were entered - LinkedHashSet is ideal to do this.
