| 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.
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 :-
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | 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("================================");
}
}

Hey, I am Parthe Omkar
Can someone explain the code line by line, I've been trying to figure out what each line does? Having the solution is nice but it's useless if you can't understand it and internalize it.
Well I'm so confused. this makes no senus at all...you guys are fucked up
