Read line N from a File

Question

Hi!
I don't now how can I read for example line number 5 of a file, this is the way I do , but it doesn't work. What the programme should do is read the first line and then read line number 5, but it read line number 2!!!
Could someone help me or paste a code ?
This is my code:
file = new File("fich");
try{
fileR = new FileReader(file);     
catch(FileNotFoundException e){}
BufferedReader bfr = new BufferedReader(fileR);
LineNumberReader lnr = new LineNumberReader(bfr);
String line=null;
line=lnr.readLine();
System.out.println("Line number:: " + lnr.getLineNumber());
System.out.println(" ----> " + line);
lnr.setLineNumber(5);
System.out.println("Line number:: " + lnr.getLineNumber());
line=lnr.readLine();
System.out.println("Line number:: " + lnr.getLineNumber());
System.out.println(" ----> " + line);
Thanks

Answer 1

I was looking through the bug reports (see 4178689) and this is what I found in the answer:
"The line number kept in LineNumberReader is not the same as the physical line
number in the input file. It is just a local counter in the reader. Setting
this number only results in the reader start counting from a new number from
the next readLine(), it does not allow jumping from one line to another in
the physical data file. The readLine() call just read lines one after another
from the underlying stream, unless reset() or skip() is called."
rbelovoskey presented a quick work-around:
public void navigateForwardToLine(LineNumberReader lineNumberReaderIn, int intLineToGoTo)
int intInitialLine = lineNumberReaderIn.getLineNumber();
try{
   for( int intCurrentLine = intInitialLine; intCurrentLine < intLineToGoTo; intCurrentLine++)
        lineNumberReaderIn.readLine();
   }catch(IOException ioe){
     ioe.printStackTrace();
