Question

(Remove duplicates) Write a method that removes the duplicate elements from an array list of integers using the following header: public static void removeDuplicate(ArrayList < Integer > list) Write a test program that prompts the user to enter 10 integers to a list and displays the distinct integers in their input order separated by exactly one space. Sample Run 1 Enter ten integers: 34 5 3 5 6 4 33 2 2 4 The distinct integers are 34 5 3 6 4 33 2 Sample Run 2 Enter ten integers: 3 3 4 4 1 1 2 2 5 5 The distinct integers are 3 4 1 2 5 Sample Run 3 Enter ten integers: 1 2 2 3 4 5 6 7 8 8 The distinct integers are 1 2 3 4 5 6 7 8 Sample Run 4 Enter ten integers: 5 4 3 2 65 4 4 5 1 5 The distinct integers are 5 4 3 2 65 1 Class Name: Exercise11_13 If you get a logical or runtime error, please refer https://liveexample.pearsoncmg.com/faq.html.
