Write a java method named flipLines that accepts as its parameter a Scanner for an input file and that writes to the console the same file\'s contents with successive pairs of lines reversed in order. Solution public static void flipLines(Scanner input) { while (input.hasNextLine()) { String first = input.nextLine(); if (input.hasNextLine()) { String second = input.nextLine(); System.out.println(second); } System.out.println(first); } }.

1. Write a java method named flipLines that accepts as its parameter a Scanner for an input file and
that writes to the console the same file's contents with successive pairs of lines reversed in order.
Solution
public static void flipLines(Scanner input) {
while (input.hasNextLine()) {
String first = input.nextLine();
if (input.hasNextLine()) {
String second = input.nextLine();
System.out.println(second); }
System.out.println(first); } }
