Read in N Lines of an Input Stream and print in reverse order without using array or list type structure?

Question

Using the readLine() method of BufferedReader, can you print the first N lines of a stream in reverse order without using a list or an array?

Answer 1

I think you can do it through recursion with something like:

void printReversed(int n)
{
   String line = reader.readLine();

   if (n > 0)
     printReversed(n-1);

   System.out.println(line);
}
