Array List

Definitions

1. A list implementation backed by a dynamically resized array, providing fast indexed access and amortized-efficient append operations. Array lists are a common default collection type when order matters and insertions in the middle are relatively infrequent.

   In plain English: A resizable list stored in array form for fast index-based access.

   Example: "The team switched from a linked structure to an array list because most operations were simple appends and indexed reads."
