How can I replace values in a JSON object in java?

This is the initial json data.

{"type":"record", "users":[{"name":"user1","type":"string"},{"name":"user2","type":"string"},{"name":"user3","type":"string"}]}


I need to replace the values in "users" with the following value.

{"user":"user4","type":"string"}


Final output should be:

{"type":"record", "users":[{"user":"user4","type":"string"}]}


Is there a direct method for this in Java?

Right now I am just emptying the original json object using 'for' loop and 'remove()' and add the string after converting it to json object using 'put()'.

JSONArray jarray = new JSONArray();
jarray = jsonobj.getJSONArray("users"); //jsonobj is the original json object
for(int i=0; i<jarray.length(); i++)
{
jsonobj.getJSONArray("users").remove(i);
}
jsonobj.getJSONArray("users").put(0,new_jsonobj);
//new_jsonobj contains the string


use a json parser, parse the string, replace the value with your custom value, create a json out of it again

Another option would be to use a regex

Please showcase what you have tried. Also, as a general question, you can deserialize the json into a map and update the value.

It looks like you want us to write some code for you. While many users are willing to produce code for a coder in distress, they usually only help when the poster has already tried to solve the problem on their own. A good way to demonstrate this effort is to include the code you've written so far, example input (if there is any), the expected output, and the output you actually get (console output, tracebacks, etc.). The more detail you provide, the more answers you are likely to receive. Check the FAQ and How to Ask.
