Pretty print JSON using org.json library in Java?
The JSON is a lightweight, text-based and language-independent data exchange format. A.JSONObject can parse text from a string to produce a map-like object. The object provides methods for manipulating its contents, and for producing a JSON compliant object serialization. The files in the org.json package implement JSON encoders/decoders in Java. It also includes the capability to convert between JSON, XML, HTTP headers, Cookies, and CDL.
We can pretty-print a JSON using the toString(int indentFactor) method of org.json.JSONObject class, where indentFactor is the number of spaces to add to each level of indentation.
Syntax
public java.lang.String toString(int indentFactor) throws JSONException
Example
import org.json.*;
public class JSONPrettyPrintTest {
public static void main(String args[]) throws JSONException {
String json = "{" +
"Name : Jai," +
"Age : 25, " +
"Salary: 25000.00 " +
"}";
JSONObject jsonObj = new JSONObject(json);
System.out.println("Pretty Print of JSON:");
System.out.println(jsonObj.toString(4)); // pretty print json
}
}Output
Pretty Print of JSON:
{
"Salary": 25000,
"Age": 25,
"Name": "Jai"
}
