Java Output Formatting – Hacker Rank Solution

 

Problem :-

Java’s System.out.printf function can be used to print formatted output. The purpose of this exercise is to test your understanding of formatting output using printf.To get you started, a portion of the solution is provided for you in the editor; you must format and print the input to complete the solution.

Input Format :-

Every line of input will contain a String followed by an integer.
Each String will have a maximum of 10 alphabetic characters, and each integer will be in the inclusive range from 0 to 999.

Output Format :-

In each line of output there should be two columns:
The first column contains the String and is left justified using exactly 15 characters.
The second column contains the integer, expressed in exactly 3 digits; if the original input has less than three digits, you must pad your output’s leading digits with zeroes.

Sample Input :

java 100
cpp 65
python 50

Sample Output :

================================
java           100 
cpp            065 
python         050 
================================

Explanation :

Each String is left-justified with trailing whitespace through the first 15 characters. The leading digit of the integer is the16th character, and each integer that was less than 3 digits now has leading zeroes.

Solution :-

 import java.util.Scanner;

 public class Solution {

    public static void main(String[] args) {
            Scanner sc=new Scanner(System.in);

            System.out.println("================================");
            for(int i=0;i<3;i++){
                String s1=sc.next();
                int x=sc.nextInt();
                System.out.printf("%-15s", s1);
                System.out.printf("%03d%n", x );
            }
            System.out.println("================================");

    }
 }
