Hello, I'm in need of some help. I have a program almost done and I could use some help to finish part of the requirement. I already have the first one done, its the second one I don't have done. Pretty much the program takes in numbers from the users, allows us to save the list made, and able to load the list back up. But it is also supposed to remove odd numbers, and right now it doesn't remove the odd numbers. Help please! Thank you!

"1. complete the NumberList class: fix the removeOdd() method so that it removes all odd numbers from the list.

2. complete the NumberListTest class: write a good unit test for the removeOdd() method so that we can make sure it works as it is supposed to."

//NumberList.java

package inclass;

import java.util.ArrayList; import java.util.Iterator; import java.util.List;

public class NumberList { private List numbers;

public NumberList() { numbers = new ArrayList<>(); }

public int add(int a, int b) { return a + b; }

public void add(int i) { numbers.add(i); }

/* * The remove(int) method will remove the specified value from the numbers * list and return true - if an item was removed false - if nothing was * removed. */ public boolean remove(int i) { Integer nr = i; if (numbers.contains(nr)) { return numbers.remove(nr); } else return false; }

/* * The getNumbers method will return a copy of the numbers list */ public List getNumbers() { return new ArrayList<>(numbers); }

/* * The isEqual(List) method will compare an input list with the * numbers list and return true - if the two are equal false - if they are * not equal */ public boolean isEqual(List list) { return numbers.equals(list); }

/* * The removeOdd method should remove all odd numbers from the numbers list * and return true - if one or more items were removed false - if nothing * was removed. */ public boolean removeOdd() { boolean result = false; Iterator itera = numbers.iterator();

while (itera.hasNext()) {

Integer in = itera.next();

if (in.intValue() % 2 == 1) { itera.remove(); result = true; } } return result; }
