/* The challenge here is to read nn lines of input until you reach EOF, then number and print all nn lines of content. Hint: Java's Scanner.hasNext() method is helpful for this problem. Input Format Read some unknown nn lines of input from stdin(System.in) until you reach EOF; each line of input contains a non-empty String. Output Format For each line, print the line number, followed by a single space, and then the line content received as input: k This is the line read as input for line number 'k'. Sample Input Hello world I am a file Read me until end-of-file. Sample Output 1 Hello world 2 I am a file 3 Read me until end-of-file. */ import java.io.*; import java.util.*; public class EndOfFile { public static void main(String []args) { Scanner sc = new Scanner(System.in); int i=1; while (sc.hasNext()) { String s=sc.nextLine(); System.out.println(i + " " + s); i++; } } }
