How to detect new line while reading file

I'm trying to read from a file which works fine. But when I reach to where in the file it skips to the next line (or makes a newline), I'm trying to find the escape character '\n', but it never mentions it.

import java.io.File;
import java.io.IOException;
import java.io.FileInputStream;

public static void main(String args[]) {
       File file = new File("Directory to file");
       try {
           FileInputStream fis = new FileInputStream(file);
           char current_char;
           while (fis.available() > 0) {
               current_char = (char) fis.read();
               if (current_char == '\n') {
                  System.out.println("We found the newline!!");
               }
            }
       }
       catch (IOException ex) {
         ex.printStackTrace();
       }
}

And the file it reads from contains this:

  This is the first line!
  This is the second line!

Different platforms use different characters for new lines. You should better check the character's type instead of comparing to any literal:

if (Character.getType(current_char) == Character.LINE_SEPARATOR) {   
   System.out.println("We found the newline!!");
}
