How to parse JSON in Java
(36 answers)
Closed 2 years ago.
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.

I receive this string in json format from my frontend:
{"hosts":[{"name":"localhost"},{"name":"localhost"},{"name":"localhost"}]}
What I want to do is to iterate each one of the hosts and print their name.
How do I map my string to do that using java?
You can convert String to JsonObject with Gson
Other option: use Jackson lib to convert Json string to Java Object

how to detect operating system language (locale) from java code
(4 answers)
Closed 4 years ago.
I'm not sure if this is possible off-hand so bear with me. I'm trying to use no external API calls from Java and determine the users language and somehow show translated strings.
Is this something you can do in Java without getting the data from online or something similar? I'm trying to make it available as an offline application but I just don't know how.
Edit:
I'm looking for a way to check with only the standard Java API's
How about something like this:
LanguageTest lt = new LanguageTest();
System.out.println(lt.getGreeting());
private class LanguageTest{
String lang = Locale.getDefault().getLanguage().toLowerCase();
public String getGreeting(){
return (lang.contains("fr") ? "Bonjour" : "Hello");
}
}
In the above example if the language is not french it will default to english.

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);

Reading binary file and looping over each byte [duplicate]
(13 answers)
Closed 9 years ago.
We had DataInputStream for processing binary files in Java; what can we use for these files in Python?
I have used the Construct package a lot to read and parse structures data in Python.
Basically it lets you declare the file's structure in a very idiomatic and pythonic way and than parses or encode it for you.
After parsing you have an object that allows access to all the file's information via attributes.
open("file", "b") opens the file and you can read it. See here.
Few years ago I used struct module to parse binary responses from several game servers http://docs.python.org/2/library/struct.html#struct.unpack
Sometimes it's usefull just to .find() some bytes in data, like .find('\x00') to go to the end of NULL-terminated string.
