Answer
public static void main(String[] args) { Scanner in = new Scanner(System.in); System.out.printf("Please specify how many lines you want to enter: "); String[] input = new String[in.nextInt()]; in.nextLine(); //consuming the <enter> from input above for (int i = 0; i < input.length; i++) { input[i] = in.nextLine(); } System.out.printf("nYour input:n"); for (String s : input) { System.out.println(s); } }
Sample execution:
Please specify how many lines you want to enter: 3 Line1 Line2 Line3 Your input: Line1 Line2 Line3
