Java Output Formatting || Hackerrank Solution

 Java Output Formatting:

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  alphabetic characters, and each integer will be in the inclusive range from  to .

Output Format

In each line of output there should be two columns:
The first column contains the String and is left justified using exactly  characters.
The second column contains the integer, expressed in exactly  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  characters. The leading digit of the integer is the  character, and each integer that was less than  digits now has leading zeroes.

• Solution

import java.util.Scanner;

public class Solution {

    public static void main(String[] args) {

        Scanner scan = new Scanner(System.in);

        System.out.println("================================");

        for (int i = 0; i < 3; i++) {

            String s1 = scan.next();

            int x = scan.nextInt();

            System.out.format("%-15s%03d%n", s1, x);

        }

        scan.close();

        System.out.println("================================");

    }

}
