How do I read only one line of text file?

Question

My program is reading all lines in the file but i just need the second one.

String line;
try (
    InputStream fis = new FileInputStream(source);
    InputStreamReader isr = new InputStreamReader(fis, Charset.forName("UTF-8"));
    BufferedReader br = new BufferedReader(isr)) {  
    while ((line = br.readLine()) != null) {
       System.out.println(line);
    }
}

If you only need the second line and you are sure the file always has at least two lines, you can just read twice and ignore the first time.

br.readLine(); //read, but ignore
System.out.println(br.readLine()); // read and output

Is there a universall method to do this? I could use this method in other classes too but for lines 8-20 and to call br.readLine(); 8 times is unnecessary. – Kozek May 19 '17 at 18:34
