❌ A. [1, 2] ✅ B. [1] ❌ C. [2] ❌ D. [] ❌ E. The code does not compile ❌ F. None of the above
Explanation: Be careful when autoboxing into Integer. It actually outputs [1]. After adding the two values, the List contains [1, 2]. We then request the element with index 1 be removed. That’s right: index 1. Because there’s already a remove() method that takes an int parameter, Java calls that method rather than autoboxing. If you want to remove the 1, you can write numbers.remove(new Integer(1)) to force wrapper class use.
