Java, No Tears

Preface

This book is to teach students how program in Java 12. To follow along and execute the code samples, you will need Docker installed. The Docker container is located on Docker Hub. After you have installed Docker, you may run the container as follows.

docker run -it \
 -p 8888:8888 \
 oneoffcoder/book-java-intro

Note that this Docker container has Jupyter Lab running on port 8888. You may access Jupyter Lab at http://localhost:8888 when the Docker container is running.
