I got the following response from the server using Java
{"success":true,"errors":[],"requestId":"blah blah","warnings":[],"result":[{"id":1023,"name":"Email","description":"", subject":{"type":"Text","value":"Some value"}}]
I want to access the id and subject's -> value. Thanks in advance.
You can use this library
JacksonXML
To parse this JSON response to Java object, and next validate it, in your custom conditions.
There are also similar libraries like gson from Google or Xpath. I recommend Jackson because Spring framework use this and it's very easy to use in production grade.

How do I map my string to do that using java?
You can convert String to JsonObject with Gson

Apple pList form of XML can I parse it through Android Java? [closed]
(6 answers)
Closed 9 years ago.
I have an app for the iPhone and now I want to use it on Android. The problem is: I can't work with the given XML-File.
Here's a link to the XML-File
Normally I would go through every node, but this won't work here since it seems like a key-value xml-file that also contains arrays.
How can I achieve it in Android/Java now that I can read this data.
This type of XML file is called plist in iOS and OS X - short for property list. The easiest way to deal with it is by using XMLWise library. It's open source and is hosted on code.google.com - here is the link.
It has a simple method for reading in the entire file and parsing it into a HashMap, something like this:
String xmlData = ...;
HashMap<?, ?> hashMap = (HashMap<?, ?>) Plist.objectFromXml(xmlData);

Hello there,
I would like to ask you, if exist some way how to convert string "1+2+3" to math equation? Exist for this purpose some function or method in Java?
Thanks for hints.
It's not part of the standard API.
But I implemented it in my project, you can have a look here.
https://github.com/MarkyVasconcelos/Towel/wiki/Expression
This would necessarily depend on the implementation of the Equation class you're using. Check its API.
