I need to pad zeros but I don't know how

Question

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.println(""+s1+"\t\t"+x);
                //Complete this line
            }
            System.out.println("================================");

    }
}

The expected output is

java	100
cpp	065
python	050

I tried to get solutions
