The Problem

You don’t know how to parse JSON in Java.

The Solution

You can easily use the org.json library to parse JSON in Java.

First, include the following dependency in your project:

Click to Copy

<dependency>
    <groupId>org.json</groupId>
    <artifactId>json</artifactId>
    <version>20210307</version>
</dependency>

Then, you can use the org.json library and the JSONObject class to parse a JSON string:

Click to Copy

import org.json.JSONObject;

class Main {
    public static void main(String[] args) {
        String jsonString = "{\"name\":\"Abdul\", \"age\":20}";
        JSONObject jsonObject = new JSONObject(jsonString);

        String name = jsonObject.getString("name");
        int age = jsonObject.getInt("age");

        System.out.println("Name: " + name);
        System.out.println("Age: " + age);
    }
}

In this example, the JSONObject class is used to parse the JSON string and turn it into a JSONObject object.

Once you have a JSONObject object, you can use the getXXX methods, like getString and getInt, to extract data from it.

Depending on your requirements, other libraries like Gson are also available for working with JSON in Java.
