What disadvantages can occur when using ArrayList for frequent maximum value searches and rare addition operations?

Using ArrayList for frequent maximum value searches and rare addition operations has the following disadvantages:

• Maximum search — O(n): ArrayList does not store elements in sorted order, so finding the maximum value requires traversing the entire list, which is inefficient for large data volumes.
• Lack of maximum caching: if the maximum value is not stored separately, each search will be costly.
• Adding elements — amortized O(1): addition is usually fast, but this is not critical for rare operations.

If maximum search is a frequent operation, it is better to use data structures that support quick access to the maximum, such as a heap (PriorityQueue) or maintain an additional variable with the current maximum, updating it when adding elements.
