- I used most of the time playing around with different libraries to work with Json. I started out using gson but realized that it's not appropriate for our use case as it relies on the use of objects. I then switched to Json from json.org.
- I also spent some time adding those dependencies. I added the jar files manually, next time I would probably invest the time in using Maven.
- If I had more time I would also look up how to avoid having to add the libraries on the classpath when executing the code.
- if not yet installed, install Java 11 by calling
sudo apt-get install openjdk-11-jdk - navigate into the src folder of the project
- to compile:
javac -cp .:../json-20210307.jar:../commons-lang3-3.12.0.jar Main/Main.java - to run:
cat path-to-json-file.json | java -cp .:../json-20210307.jar:../commons-lang3-3.12.0.jar Main/Mainwherepath-to-json-file.jsonis for instance../basic.jsonfor the test file I added for testing purposes
