Implementation

Implement a log analyzer: open file, read lines, count errors, and summarize results.

Intro

Implementation means coding the design: open log files, process lines, and produce summaries.

File reading setup

We use Files.newBufferedReader to read logs line by line. Each line can then be parsed for keywords.
