Lists and Arrays Performance Recap
The lesson reviews the benchmark bar charts to summarize the relative performance of ArrayList, unsized List, pre-sized List, and integer array, confirming that pre-sizing yields roughly a 2x speedup over a default-sized list. We give practical guidance on when to prefer arrays over lists in mission-critical code.
