Conditional Element Removal with ArrayList and Iterator

In this problem, you will implement a method removeEvens that safely removes even numbers from a range of integers using an Iterator and returns the remaining odd numbers as a comma-separated string.

Learning Objective: Understand safe element removal using Iterator and advanced ArrayList operations

Specification

Class Design

• Method: public static String removeEvens(int start, int end)
  • Add integers from start to end to an ArrayList<Integer>
  • Use an Iterator to safely remove even numbers
  • Return the remaining elements joined by ", "

Examples

removeEvens(1, 8) → "1, 3, 5, 7"
removeEvens(10, 15) → "11, 13, 15"
