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.

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.

Parse any date in Java

Is there an equivalent in java to python functions that can parse date/time input without giving the format as an argument?
I want to be able to receive an input and determine if it's a time stamp of some sort. Is it necessary to manually go over all common patterns?
dateparser is a neat utility which might fit your case

Guessing the encoding of text represented as byte[] in Java
(7 answers)
Closed 8 years ago.
I'm receiving a byte[] of information in an unspecified encoding format. Is there a way to convert it to a String without knowing the character encoding?
The tool of choice is CharsetMatch from ICU: http://userguide.icu-project.org/conversion/detection
It is not an exact science, so there is a confidence score that you have to watch and it will take some experimentation, but will definitely get you where you want to go. Good Luck!

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);

I'm having a list of Integer from 1 to 100. If I loop through the list, I wanted to make the output as,
"One"
"Two" .....
"Hundred"
Is there any direct method in Java to obtain the above output?
No such method or class has been provided by JDK.
You can use the code mentioned here or here for reference purpose.
switch case are used to meet that requirement: Here
is source code.
Answer of this question described here: How to convert number to words in java
Officially this is not possible or no standard library available by native Java.
Don't duplicate.
There is none in the official Java libraries. However, the International Components for Unicode project has a RuleBasedNumberFormat with those capabilities. It even has a SPELLOUT constant.
