Great job on implementing the ArrayList class! 🎉 Your code meets the task requirements and constraints, and you've done well to follow the checklist guidelines. While there are a couple of minor improvements suggested, such as using equals() for object comparison and checking for null or empty lists in the addAll method, these do not critically impact the functionality. Keep up the good work, and consider these suggestions for future enhancements! 😊

Using == to compare objects is incorrect for non-primitive types. Use equals() to compare the elementData[i] with element to ensure proper object comparison.

Consider adding a check for null or empty lists in the addAll(List<T> list) method to avoid unnecessary operations.
