/* "In computing, End Of File (commonly abbreviated EOF) is a condition in a computer operating system where no more data can be read from a data source." — (Wikipedia: End-of-file) The challenge here is to read lines of input until you reach EOF, then number and print all lines of content. Hint: Java's Scanner.hasNext() method is helpful for this problem. Input Format Read some unknown 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. 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 Solution { public static void main(String[] args) { /* Enter your code here. Read input from STDIN. Print output to STDOUT. Your class should be named Solution. */ Scanner sc=new Scanner(System.in); for(int n=1;sc.hasNext()==true;n++){ String s=sc.nextLine(); System.out.println(n+" "+s); } } }
