The code above reads each line of input using a for loop and the Scanner class. It then extracts the string and integer using the next() and nextInt() methods of the Scanner class. The string and integer are then formatted using the String.format() method. Specifically, the string is left-justified using the % and - format specifiers to indicate that the string should be left-aligned, and the integer is formatted using the %03d format specifier, which pads the integer with leading zeroes if necessary to make it three digits long.

Finally, the formatted output is printed to the console using the System.out.println() method. After all input lines have been processed, the program prints a separator line consisting of 32 equals signs to visually separate the output from the input.

Note that the code above assumes that there will be exactly three lines of input. If there could be more or fewer input lines, you should modify the loop condition accordingly.

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();
             String output = String.format("%-15s%03d", s1, x);
        System.out.println(output);
        }
        System.out.println("================================");

}
