Output_Formatting.java

/*
-----------------------------------------------------Problem Statement--------------------------------------------------------

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 15th characters. The leading digit of the integer is the  character, and each integer that was less than 3 digits now has leading zeroes.

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%03d%n",s1,x);   
                  //("%-15s%03d%n", s1, x) % : used as a formatter. '-' : minus sign used for left indentation of the string. 15s : here 15 denotes the string's minimum field width 15. '0' : pads the extra 0s in the integer. 3d : here 3 denotes integer's minimum field width 3. %n : prints the new line.
            }
            System.out.println("================================");

    }
}
