Review Summary
This is a strong submission, and you've correctly implemented most of the core functionality for the custom ArrayList. However, a few changes are needed to fully meet the task requirements based on the checklist.
Here are the required fixes:
- Informative Exceptions: The
NoSuchElementExceptionthrown in theremove(T element)method must include a descriptive message indicating which element was not found. [CHECKLIST ITEM #10] - Method Naming: The
grow()method's name is a bit misleading because it only grows the array under a specific condition. A more accurate name would begrowIfFull()orensureCapacity(). [CHECKLIST ITEM #6] - Variable Naming: The variable name
newArrayis too generic. Please consider a more descriptive name likeexpandedElementsto better convey its purpose. [CHECKLIST ITEM #6]
Once these points are addressed, your solution will be in great shape. You're very close to completing the task!

This violates checklist item #10: 'Make your exceptions informative.' This exception should include a message indicating which element was not found in the list.

This violates checklist item #6: 'Use informative names for your variables and methods.' The checklist provides an example that directly applies here. Since this method only grows the array under a specific condition (if (size == elementData.length)), a more descriptive name like growIfFull() or ensureCapacity() would better reflect its behavior.
| private void grow() { | ||
| if (size == elementData.length) { | ||
| int newCapacity = elementData.length + (elementData.length >> 1); | ||
| T[] newArray = (T[]) new Object[newCapacity]; |

This violates checklist item #6: 'Do not use abstract words like string or array as variable names.' The variable name newArray is too generic. Consider a more descriptive name like expandedElements or newElementData to better convey its purpose.

Excellent work on this submission! I'm happy to approve it. You've done a great job addressing all the feedback from the previous review. The method and variable names are now much more descriptive, and the exception messages are clear and informative. Your ArrayList implementation is clean, correct, and fully meets all the task requirements. Keep up the fantastic work!
