Data with special character when get data using InputStream data has been changed

I have a web service which returns xml document contains characters like "ÅUðSÅU". When I read this file using
InputStreamReader, it's generate string like "ÅUðâ??ÅU" .
I'm using UTF-8 but not working. My code is following-
BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream(),"utf-8"));
int value=0;
// reads to the end of the stream
while ((line = br.readLine()) != null) {
System.out.println("data--"+line);
response += line;
}

Java: ServerSocket reading data from a client

I am working on a simple programm for a university course. Here is the code that I have problems with:
//everything before this is unrelevant
String message = "";
BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));
while((message = br.readLine()) != null) {
System.out.println(message);
}
//everything after this is irrelevant
I also have a thread for accepting incoming connections and some other stuff that is irrelevant. The problem that I have is that I can read one message and after that nothing happens. I guess the readLine() method is the problem but I am not really sure how to solve it.
It even says in our assignment to use
BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));
to receive data.

Your client is only sending one line. You therefore don't need the loop. You should read one line and then do whatever you're supposed to do with it.

Getting weird characters from a web page

I am writing a program in Java that parses some text from a web page. But when I use the code below I get weird/incorrect characters.
code:
URL url = new URL(getSearchUrl(crit));
URLConnection connection = url.openConnection();
BufferedReader br = new BufferedReader(
new InputStreamReader(connection.getInputStream(), "UTF-8"));
String line;
while((line = br.readLine()) != null){
System.out.println(line);
}
br.close();
I get the following output:
?}?v?8????...
So what am I doing wrong? I know that the site I want to gather info from uses utf-8.
Edit: I am currently in Crotia. I tried some other program I know worked in Serbia (my home country) but it doesn't work here.

It's g-zipped. you can see it using connection.getContentEncoding().
If you use a GZIPInputStream around the connection.getInputStream() it should work better.
BufferedReader br = new BufferedReader(
new InputStreamReader(new GZIPInputStream(connection.getInputStream()), "UTF-8"));

display the output-stream of a Process returned by Runtime.exec()

How do I print to stdout the output string obtained executing a command?
So Runtime.getRuntime().exec() would return a Process, and by calling getOutputStream(), I can obtain the object as follows, but how do I display the content of it to stdout?
OutputStream out = Runtime.getRuntime().exec("ls").getOutputStream();
Thanks

I believe you are trying to get the output from process, and for that you should get the InputStream.
InputStream is = Runtime.getRuntime().exec("ls").getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader buff = new BufferedReader (isr);
String line;
while((line = buff.readLine()) != null)
System.out.print(line);
You get the OutputStream when you want to write/ send some output to Process.

Convert the stream to string as discussed in Get an OutputStream into a String and simply use Sysrem.out.print()

Substitute for Scanner when using Sockets

Is there a better substitute for Scanner class when using sockets? i am getting really tired of the .next() and .nextLine() that are really annoying to work with because they skip lines all the time.

Use InputStreamReader along with BufferedReader
Eg:
Socket s = new Socket("10.0.0.1",4444);
InputStreamReader isr = new InputStreamReader(s.getInputStream());
BufferedReader br = new BufferedReader(isr);
String str = new String();
while ((str = br.readLine())!=null){
System.out.println(str);
}
