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.
Solution:
import java.io.*;import java.util.*;
public class Solution {
public static void main(String[] args) { String str=""; int i=1; Scanner s=new Scanner(System.in); while(s.hasNext()){ String m=s.nextLine(); System.out.println(i+" "+m); i++; } }}
