netbeans - reading text file with utf-8 encoding using java

Question

I have problem in reading text file with utf-8 encoding I'm using java with netbeans 7.2.1 platform

I already configured the java project to handle UTF-8 javaproject==>right click==>properties==>source==>UTF-8

but still get the unknown character output: ????? ???????? ???? ?

the code:

File fileDirs = new File("C:\file.txt");

BufferedReader in = new BufferedReader(
new InputStreamReader(new FileInputStream(fileDirs), "UTF-8"));

String str;

while ((str = in.readLine()) != null) {
    System.out.println(str);
}

any other ideas?

thanks

Use

    import java.io.BufferedReader;
    import java.io.File;
    import java.io.FileInputStream;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.io.UnsupportedEncodingException;     
    public class test {
    public static void main(String[] args){

    try {
        File fileDir = new File("PATH_TO_FILE");

        BufferedReader in = new BufferedReader(
           new InputStreamReader(new FileInputStream(fileDir), "UTF-8"));

        String str;

        while ((str = in.readLine()) != null) {
            System.out.println(str);
        }

                in.close();
        } 
        catch (UnsupportedEncodingException e) 
        {
            System.out.println(e.getMessage());
        } 
        catch (IOException e) 
        {
            System.out.println(e.getMessage());
        }
        catch (Exception e)
        {
            System.out.println(e.getMessage());
        }
    }
}

You need to put UTF-8 in quotes
