Java Programming

Please help me with this project. It should be related to Polymorphism.

Please do not give me some answers that are already posted by others. I already saw those codes. I want to see some other works. It could be similar method and idea.

Write a method that removes the duplicate elements from an array list of integers using the following header:

public static void removeDuplicate(ArrayList list)

Write a test program that prompts the user to enter 10 integers to a list and displays the distinct integers separated by exactly one space. Here is a sample run:

Enter ten integers: 10 20 30 20 20 30 50 60 100 9

The distinct integers are: [10, 20, 30, 50, 60, 100, 9]
