Well it seems that you are not doing it as you appear not to have started yet. Or do I misunderstand and you have completed most of the project and are just stuck on one problem?

If you have not started then I doubt that you are going to complete it in 5 days.

BTW saying that it is urgent is unlikely to get people to write it for you.

It's time for a new signature.

Hello Friends
I am reading a file Like this here is the code below:

FileInputStream in = new FileInputStream(file);
Reader r = new InputStreamReader(in, "ISO-8859-1");
int intch;
while ((intch = r.read()) != -1) {

  int temp = intch;

}

Previously I was putting all data into another file char by char like this

OutputStream out = new FileOutputStream(outFilePath);
and using out.write(temp); in while  loop

And it was working fine.
But now The value coming in temp ,I want to store in a string.temp contains some int value of that charset and I want tht in string.

Any Suggestions??
Thanks In Advance.

Yogesh

Or Is there any way to read file line by line thru BufferedReader whose data is in ISO-8859-1 charset.

I tried like this even

this(new BufferedReader(new InputStreamReader(new FileInputStream(file),"ISO-8859-1")));

but bufferedReader is coming null.

Any Ideas??

Regards
Yogesh

I'm kind of new to this whole Java thing but there is a readLine() method on BufferedReader. How about something like this? ISO-8859 is a standard 8 bit character encoding so you shouldn't have problems reading the file.

<br />
String line;<br />
BufferedReader br = new BufferedReader(new FileReader(fileName));<br />
<br />
while ((line = br.readLine()) != null) {<br />
   // do stuff with line<br />
}<br />
<br />
br.close();<br />

I already Tried like this but bufferedReader is coming null.
And moreover it would be better if somebody suggest how can I convert each ISO-8859-1 character into String Bcoz I have to do some decoding for each character.
Thanks

What do you mean "bufferedReader is coming null"?

If I do this:

BufferedReader br = new BufferedReader(new FileReader(fileName));

then either I will get a BufferedReader created or I will get a FileNotFoundException. I can't quite see how you are getting a null here.

If file encoding is a problem for you then use InputStreamReader:

Json -> java object

Hi
There is no problem to convert JSON which looks like this:
"{\"response\": {\"Code\":200, \"Text\":\"Ok\", \"Id\":\"123\"}}
to the following object:

public class JsonCL
{
    private int Code;
    private String Text;
    private int Id;
    
    setters;
    getters;
}

But what about the JSON, which contains arrays of data, and nested arrays?
For example:

{\"response\": {\"Code\":200, \"Text\":\"Ok\", \"Id\":\"123\", \"data\":{\"groups\": [{\"key1\":\"value1\", \"nestedData\":[{\"key1\":\"value1\", \"key2\":\"value2\", \"key3\":\"value3\"},{\"key1\":\"value4\", \"key2\":\"value5\", \"key3\":\"value6\"}]},{\"key1\":\"value2\", \"nestedData\": [{\"key1\":\"value7\", \"key2\":\"value8\", \"key3\":\"value9\"},{\"key1\":\"value10\", \"key2\":\"value11\", \"key3\":\"value12\"}]}]}}}

How can I convert such JSON into java object?

Thanks!

Try doing your own research - start with Google "VPN Java" and go on from there. When you hit a problem then try asking a specific technical question.

So this is your final year project but you have no ideas about it, but you expect someone here to provide a solution. You need to understand that this site is setup to help people who do their own work but get stuck on technical problems or bugs. We don't have the time to provide full solutions, design specifications etc. If you really have no idea where to start with this project may I respectfully suggest you try something within your skill set.

I second that, especially looking back at his posts from about 2 years ago. He should pursue a different career perhaps.

Actually it was you who asked for help and anyone is free to comment or otherwise respond to your question. Your response is rude and unwarranted.

Hardly, and do brush up on your grammar. If you noticed, the past few posts, I'm actually trying to help you out a bit in terms of how you reply to people. I have been in I.T. for probably longer than you have been alive and the way you are behaving will not last in a corporate world environment.

You want to work on your grammar, if English is not your primary language, as I have noticed you are from Iraq and I am assuming English is new for you, so practice it and you'll succeed at it Big Grin | :-D

Also, please refrain from txtspeak gibberish because it is not a professional form of communication.

Peace out, man, and good luck in your endeavors.

Wow, with an attitude like that, good luck getting help for anyone. Also an attitude like that will not get you far in the workplace either. Looking at your previous posts and level of competency, you might want to look at different careers. Wasn't meaning to pick on you, but just suggesting.
