Utilizing Gson to Parse JSON in Java

Q: Parsing JSON Data as a String with Gson

Given a JSON string jsonLine, the task is to extract the text "Hello world" using the Gson library. The provided class, JsonParsing, contains a parse method that should accomplish this task.

A: Gson's Facile JSON Parsing

The following code snippet demonstrates how to parse the JSON string using Gson:

public String parse(String jsonLine) {
    JsonElement jelement = new JsonParser().parse(jsonLine);
    JsonObject  jobject = jelement.getAsJsonObject();
    jobject = jobject.getAsJsonObject("data");
    JsonArray jarray = jobject.getAsJsonArray("translations");
    jobject = jarray.get(0).getAsJsonObject();
    String result = jobject.get("translatedText").getAsString();
    return result;
}

This code sequence parses the JSON string, navigating through the nested objects and arrays to retrieve the desired text. For clarity, exception handling and input validation have been omitted.
