Is there a Json - parser for java online that can help me to create Java - objects from Json-string? (I found similar one but there I can translate json-string in Java -objects only if I have url for my json-string)?
Thanks for the link, this should be easy:
upload your JSON string to a site like pastebin.com
get the RAW link, i.e. the one without the PasteBin website around)
put that into http://jsongen.byingtondesign.com
Have a look at http://jackson.codehaus.org/
But be sure that you really want to put it into Java objects, because whenever the JSON representation changes, translation will break of course.
QuickType.io is exactly what you're looking for.
For the record, I'm unaffiliated.

I have a string like this:
नमस्कार
Now i want to translate the string to html entity decoder. I can translate manually by using
url https://mothereff.in/html-entities
is there any java api to translate it ?
can anyone help me ? thanks in advance
This might prove to be useful unbescape. I found it to be diverse and very quick to implement. I'm using it to convert huge lists of strings with HTML entities in them back to normal strings. It's quick and accurate so far.
It seems, after a quick google search, that a popular solution to this is using StringEscapeUtils.unescapeHtml4(). More information can be found in this Stack Overflow question.
I'm attempting to read and write an object through gson. Early in the project this was completely viable and doing great, but as I wrote more data for that object I eventually ran across something along the lines of this:
I can't seem to grab the full stacktrack seeing as it overflows my console within milliseconds, but I've pastebinned everything my console could grab: http://pastebin.com/v36d5qua
If there is a solution to this, or possibly just a better api for this purpose I would really appreciate some advice.
Current usage: http://pastebin.com/2Yk2v0Tm
GsonUtil.save(player, Player.class, new File("./resources/players/"+player.getId()+".json"));
P.S I'm new to java & this site in general, if I have misleading tags, title etc please let me know.
Don't use gson. It's slow, it's buggy, it's inconvenient to use. Just use org.json - http://theoryapp.com/parse-json-in-java/
I want to extract a list of feed information from an OPML file in java. I know I have to use some xml-parse technique, but I have no idea what to use.
I am a java beginner, so could you tell me how to do it and give me an example?
Thanks a lot!!
This should fairly straight forward. You can take one of hte following two approaches.
Use java parsing capabilities and parse it as any XML file. Here is an example using DOM parse.
There are lot of the open source code/libraries for doing this. Here is one such example. This class has a method public ArrayList<OpmlElement> readDocument(Reader reader). You can create a Reader object from the OPML file and pass the same to this function. Please note that this library depends on xml Pull parser libraries. So if you do not want to add another dependency use the first approach.
Here is another example on this forum itself.
I have a large collection of twitter messages from the streaming twitter API saved as JSON strings in text files.
I wanted to know if anyone knew how I could convert these JSON strings into something like the Twitter4J status object for use as a simple object with getters and setters?
I was thinking about debugging the source and writing my own inject class which would mimic the input stream classes, however I wonder if there is a better way..?
Thanks!
Try DataObjectFactory#createStatus(String). It's a simple static method that returns one single twitter4j.Status object.
http://twitter4j.org/en/javadoc/twitter4j/json/DataObjectFactory.html#createStatus(java.lang.String)
You can try using Google's Protobuff or Codehause's XStream or Jackson

Depends on what you want to do with the data. One thought that comes to mind is importing it into a database like MongoDb which already has support for importing JSON http://www.mongodb.org/display/DOCS/Import+Export+Tools . then you can proceed to analyse or convert the data further from there
I'm manually parsing Json objects using java and I have a problem with urls.
They currently look like this:
http:\/\/a3.sphotos.ak.fbcdn.net\/hphotos-ak-ash4\/...
and I was wondering how to decode them into a normal form that I can further use, like this:
http://a3.sphotos.ak.fbcdn.net//hphotos-ak-ash4//...
It's not just the slashes that cause this problem, so simply searching for them is not a solution.
I'm searching for a standard method from the jdk that could easily accomplish this.
Unfortunately I have know idea what the encoding is called, so I can't be more specific in what I want to know.
Looks like you should try and use the answer from here:
unEscape JavaScript escaped value in JAVA
There seems to be an unescape function. I have used that before in javascript (unescape) to help with the same issue. Looks like Java has a similar function.
