Write a program that prompts the user to enter the mass of a person in kilograms

Question

Write a program that prompts the user to enter the mass of a person in kilograms and outputs the equivalent weight in pounds.

Output both the mass and the weight rounded to two decimal places.

I need to format this in a way that my output is two decimal places. The program runs but I am missing that key aspect of the assignment. Note- 1 pound = 2.2 kilograms

import java.util.Scanner;

public class Converter {

    public static void main (String [ ] args) {

        double kilograms;

        double pounds;

        Scanner input = new Scanner (System.in);

        System.out.println ("Enter your mass in kilograms " );

        kilograms = input.nextDouble ();

        pounds = kilograms * 2.2;

        System.out.println (kilograms + "kilograms is equivalent to" + pounds + " pounds " );

     }

}

kilograms = Double.parseDouble(inputstr);

outputstr = new DecimalFormat("##.##").format(kilograms* 2.20);

JOptionPane.showMessageDialog(null, outputstr,"Weight in Pounds",JOptionPane.INFORMATION_MESSAGE);

System.exit(0);

}
