public class LineNumberInputStreamDemo {
   public static void main(String[] args) throws IOException {
      LineNumberInputStream lnis = null;
      FileInputStream fis = null;
      int i;
      
      try {
         // create new input streams
         fis = new FileInputStream("C:/test.txt");
         lnis = new LineNumberInputStream(fis);
         
         // set the line number
         lnis.setLineNumber(100);
         
         // get the current line number
         i = lnis.getLineNumber();
         
         // prints
         System.out.print("Line number: "+i);
         
      } catch(Exception e) {
         // if any error occurs
         e.printStackTrace();
      } finally {
         // closes the stream and releases any system resources
         if(fis!=null)
            fis.close();
         if(lnis!=null)
            lnis.close();      
      }
   }
}

Assuming we have a text file c:/test.txt, which has the following content. This file will be used as an input for our example program −

ABCDE

Let us compile and run the above program, this will produce the following result −

Line number: 100
