Data-Oriented Programming in Java

This project demonstrates Data-Oriented Programming (DOP) principles applied in Java 21.
It processes log files, extracts statistics, and generates a report.

Project Structure

• LogReader / FileReader
  Reads log files from disk and returns raw lines.

• LogParser / DefaultLogParser
  Parses each log line into a structured LogEvent (Error, Warn, Info, Debug).

• LogProcessor
  Coordinates reading and parsing across multiple files, using virtual threads for concurrency.

• LogStats
  Aggregates statistics from a list of LogEvent objects (counts of errors, warnings, infos, debugs).

• ReportGenerator
  Produces a human-readable report string with the statistics.

• ConsoleWriter
  Prints the report to the console.

• Main
  Entry point: loads log files from resources/logs, processes them, generates statistics, and prints the report.

Example Flow

1. Load log file paths from src/main/resources/logs.
2. Process files into LogEvent objects.
3. Generate statistics (LogStats).
4. Build a report (ReportGenerator).
5. Print to console (ConsoleWriter).
