## Overview

This is a small Swing Notepad-style editor. The workflow starts in the application entry point, opens an editor window, and lets the user edit text, search or format it, and save or open files through disk or the database. Editing capabilities are implemented within one large frame class rather than separate modules. The sampled code shows editor construction, disk saving, database access, search highlighting, and dispatch to save operations; other capabilities are documented in the README but their implementation details were not sampled.

Main entry points: [`src/EditorFrame.java`](https://github.com/raheelnaziir/text-editor/blob/main/src/EditorFrame.java) (Editor window), [`src/Main.java`](https://github.com/raheelnaziir/text-editor/blob/main/src/Main.java) (Application entry)
