July 13, 2023[Java] How can I parse a JSON string then extract values from it?
One would think you'd use the same API you're already using, the one that has JSONArray in it. Are you unable to find or understand the docs for it? Do you understand the format of the data you're getting back? Are you otherwise competent with programming in Java, or are you still unable to do small projects on your own? Do you want pseudocode or real code spoonfed to you, or an algorithm outlined for you, or just some hints about how to do it? The data you get back looks like it might have multiple pieces of data in it, so can you attempt to use a loop here somehow? Do you understand JSON? More on reddit.com

You can use:
JSONObject jsonObject = new JSONObject();
jsonObject.toString();
And if you want to get a specific value, you can use:
jsonObject.getString("msg");
or Integer value
jsonObject.getInt("codeNum");
For long Integers
jsonObject.getLong("longNum");
