To handle this just catch NoSuchElementException and return a proper message.
try {
int lineNumber = 3;
String str = Files.lines(Paths.get("/home/subash/Documents/sample.txt")).skip(lineNumber - 1).findFirst().get();
System.out.println(str);
} catch (NoSuchElementException) {
System.out.println("Element not found!");
} catch (Exception) {
e.printStackTrace();
}
