## Overview

This is a set of independent Java array and ArrayList learning examples, not a single application. The main workflows demonstrate array display, arithmetic and aggregate calculations, or basic list operations, then print results to the console. Several files duplicate class names, so their examples are best understood as separate snippets rather than a connected runtime. The graph reflects calls visible in the sampled code; no README or project-level wiring is present.

Main entry points: [`1.java`](https://github.com/amnaa-k/dsa-theory-lecture-2/blob/main/1.java) (Display examples), [`l2_src1.java`](https://github.com/amnaa-k/dsa-theory-lecture-2/blob/main/l2_src1.java) (Display and stats), [`2.java`](https://github.com/amnaa-k/dsa-theory-lecture-2/blob/main/2.java) (Array statistics), [`3.java`](https://github.com/amnaa-k/dsa-theory-lecture-2/blob/main/3.java) (Casting and stats)
