# Java Code Challenges

This project will be used to store Java Code Challenges worked on my own time.

## About This Repository

The plan is to have many Packages stored and updated here along with test libraries, readmes, and other supporting files.

While Gradle treats this repository as a single project, it is just a container for these packages and files.

Some Packages will contain core algorithm and data structures, others will contain code that relies on those core structures, completing code challenges, and implementing unit tests.

## Building and Testing Libraries

Java JDK: temurin-17-jdk-amd64

Gradle: 7.4.2

Build: `./gradlew build`

Test: `./gradlew test`

Test results pretty html output: 'java-code-challenges/lib/build/reports/tests/test/index.html'
