Java Output Formatting – HackerRank Solution

Java Output Formatting – HackerRank 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 the 16th 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();
                int a = s1.length();
                int b = 15 - a;
                System.out.print(s1);
                for (int c=0;c<b;c++)
                {
                    System.out.print(" ");
                }
                String strN = String.format("%03d", x);
                System.out.println(strN);
            }
            System.out.println("================================");

    }
}
