Using BufferedReader or Scanner for processing multiple inputs in Java

Question

When I am trying to Read all the lines by using this program...It gives me one line less as an output.

Sample Program:

String line = null;
Scanner scanner = new Scanner(System.in);
while (scanner.hasNextLine()) 
{
  line = scanner.nextLine();
  System.out.println(line);
}
scanner.close();

When I give the Standarad input as:

ab
cd
ef
gh

Output is:

ab
cd
ef

Answer 1

"scanner.hasNextLine()". The last line doesn't have a nextline, so it exists the loop before it prints out ef.
