Java End-of-file | HackerRank Solution

Hello coders, today we are going to solve Java End-of-file HackerRank Solution.

Problem

The challenge here is to read n lines of input until you reach EOF, then number and print all n lines of content.

Hint : Java’s Scanner.hasNext() method is helpful for this problem.

Input Format

Read some unknown n 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.
