Review Summary
Great job on implementing the ArrayList! Your code meets most of the task requirements, but there are a few areas for improvement:
-
Custom Exception: You need to define and implement the
ArrayListIndexOutOfBoundsExceptionclass to handle invalid index cases as specified in the task requirements. -
Index Validation: The
checkIndexForSetmethod is redundant. Consider using a single method for index validation to avoid code repetition and improve maintainability. -
Code Structure: Remove empty lines at the beginning of classes and methods, and eliminate redundant empty lines within methods to enhance readability.
-
Resizing Logic: Move the array resizing logic into a separate method, such as
resizeIfNeeded, to adhere to the Single Responsibility Principle. -
Exception Messages: Ensure that exceptions have informative messages to clearly indicate the issues.
These improvements will help you refine your code and adhere to best practices. Remember, addressing these issues is crucial for developing robust and maintainable code. Keep up the good work, and continue learning from your experiences! 😊

The method checkIndexForSet is redundant since it performs similar logic to the checkIndex method. Consider using a single method for index validation to avoid code repetition, as suggested in the checklist: "If the logic of your code repeats - move it to a separate private method."

The ArrayListIndexOutOfBoundsException class is not defined in the provided files. You need to implement this custom exception to handle invalid index cases as required by the task description.
