## Overview

This repository is a set of small Java examples about dynamic arrays and `ArrayList`, rather than a cohesive application. The examples demonstrate adding, removing, reading, replacing, searching, iterating, and checking size or initial capacity; `a_example.java` also shows shrinking an array. Each runnable example is an independent `main` program. `a.java` contains incomplete snippets, so it is not mapped as a runnable flow. There is no README, and the graph reflects only the supplied source excerpts.

Main entry points: [`b.java`](https://github.com/amnaa-khann/lab-2/blob/main/b.java) (List operations), [`b_example.java`](https://github.com/amnaa-khann/lab-2/blob/main/b_example.java) (Remove element), [`c.java`](https://github.com/amnaa-khann/lab-2/blob/main/c.java) (Append items), [`d.java`](https://github.com/amnaa-khann/lab-2/blob/main/d.java) (Replace element)
