 In a class called ArrayListPractice Create an arraylist of integers and fill it with the values 6,2,7,3,12,1, 9, 9, 3, 5, 9   Create a method removeNines that will remove every 9 from the list. Create a method called public void replaceWithRandom (int k) that will find all instances of k and replace it with a random number between 0 and k Create a method called makeEven that will make all even (either staying if even, or moving up one if odd) (so 6 would become 6, 7 would become 8, 9 would become 10) Create a method called public void addZeros (int k) that will add k zeroes after every instance of k, so if k was 3, it would add three elements 0,0,0 after k. For advanced create a method that will return as an arraylist, all numbers that repeat. For advanced create a method that will return the data as an array of ints   Starter code: ```import java.util.ArrayList; public class ArrayListPractice { ArrayList myList=new ArrayList(); public ArrayListPractice() { //6,2,7,3,12,1, 9, 9, 3, 5, 9 myList.add(6); myList.add(2); myList.add(7); myList.add(3); myList.add(12); myList.add(1); myList.add(9); myList.add(9); myList.add(3); myList.add(5); myList.add(9); } public static void main (String[] args) { ArrayListPractice a=new ArrayListPractice(); } } ```
