# Getting Started

## What This Project Does
This codebase is a small Java repository that appears to focus on source patterns and field definitions rather than a full application stack. The current entry points are simple classes under `src/main/java`, so the best way to get oriented is to read the files directly and understand the naming and annotation/comment conventions used here.

## Recommended Reading Order
1. **Start here:** this guide, then the source files in `src/main/java`.
2. **Read next:** [PatternA](../src/main/java/PatternA.java) and [PatternB](../src/main/java/PatternB.java) to see the two main code styles used in the repo.
3. **Then read:** [Mixed](../src/main/java/Mixed.java) to compare the “patterned” and “plain” styles side by side.

## Key Entry Points
There are no highly referenced classes identified in this repository, so begin with the visible Java files:
- [PatternA](../src/main/java/PatternA.java) — shows a single field wrapped with `ADD START` / `ADD END` markers.
- [PatternB](../src/main/java/PatternB.java) — shows a static field map with inline Japanese comments.
- [Mixed](../src/main/java/Mixed.java) — shows a simpler class with minimal annotation.

## Project Structure
- `src/main/java/` — primary source directory.
- `PatternA.java`, `PatternB.java`, `Mixed.java` — current Java classes in the repository root source tree.

At this stage the repository is very small, so the fastest way to understand it is to read each file in full and compare how fields, comments, and naming conventions differ.

## Configuration
No dedicated build, application, or environment configuration files were found in the current repository snapshot. If you add more modules later, check first for standard Java project files such as `pom.xml`, `build.gradle`, or config directories under `src/main/resources`.

## Common Patterns
- **Simple Java classes:** each file declares one public class with a small number of fields.
- **Comment markers:** `PatternA` uses `// ANK-0001 ADD START` / `END` markers to delimit generated or maintained code sections.
- **Field mapping tables:** `PatternB` uses a `String[][]` constant to map field names to types.
- **Localized comments:** some comments are in Japanese, so it helps to preserve the original wording when editing.
- **Minimal abstraction:** there are no helper layers, inheritance hierarchies, or framework-specific patterns yet, so changes should stay consistent with the existing straightforward style.

## Suggested First Steps
- Open [PatternA](../src/main/java/PatternA.java) and identify which code is protected by markers.
- Open [PatternB](../src/main/java/PatternB.java) and note how constants are structured.
- Open [Mixed](../src/main/java/Mixed.java) to see the baseline style for simple classes.
