In this video, I show you exactly how to parse JSON in Java and turn data from a JSON file into a clean, usable Java object. This is one of those super common tasks, and once you set it up the right way, it’s honestly just a few lines of code. I walk you through the full flow: getting the JSON library into your project, reading the JSON file safely, and deserializing it into a Java class so you can work with real objects instead of raw text. I use Google’s Gson library here and demonstrate a manual setup (downloading the JAR from the Maven repository, dropping it into a /lib folder, and adding it to the build path in IntelliJ). After that, I show a simple example with a user data.json file and a Player class. The key takeaway is that your Java field names need to match the JSON keys so Gson can map everything automatically. Then I read the JSON using a try-with-resources block (so readers close automatically), call fromJson(bufferedReader, Player.class), and print the object properties to confirm it worked.
