JSON Flattener

A Java program taking JSON input and outputting a flattened JSON object.

Prerequisites

• Install Java Development Kit (JDK)
  • Includes:
    • Java Compiler - For compiling Java source code
    • Java Runtime Environment (JRE) & Java Virtual Machine (JVM) - For running Java byte code
  • Downloads & Platform Specific Instructions:
    • Oracle JDK Installation Guide

Compile and Run the Program

1. Open a terminal window (e.g. GitBash) and change the directory to where you want to place the cloned repo.
2. Clone the repo

# using ssh
git clone git@github.com:elle-j/JSON-Flattener.git

# using https
git clone https://github.com/elle-j/JSON-Flattener.git

3. Change directory to the source code directory

cd ./JSON-Flattener/java-program/src/

4. Compile the source code

javac -cp . ./dev/ellej/*.java

5. Run the program

# replace <json_object> with a valid JSON object
java dev.ellej.Main <json_object>

# example 1:
java dev.ellej.Main '{ "a": 1, "b": true, "c": { "d": 3, "e": "test" } }'

# example 2:
cat /path/to/file.json | java dev.ellej.Main

Assumptions

• The program will always receive an input when run
• The input will always be a valid JSON object
• The JSON object will not contain arrays
