Question

java language NetBeans

Write a program that prompts the user to enter the weight of a person in kilograms and outputs the equivalent weight in pounds. Output both the weights rounded to two decimal places. (Note that 1 kilogram = 2.2 pounds.) Format your output with two decimal places.

Answer 1

I have created java application named WeightConversion in NetBeans IDE

package weightconversion;

import java.util.*;

public class WeightConversion {

    public static void main(String[] args) {

        //declare variables
        double kg_weight, pound_weight;
        Scanner sc = new Scanner(System.in);

        System.out.print("Enter the weight of the person in kilograms: ");
        //takes weight entered by user and stores it in a kg_weight variable
        kg_weight = sc.nextDouble();

        //convert kg to pound
        pound_weight = 2.2 * kg_weight;

        //String.format("%.2f",value) is used to round the value upto two digits after point
        System.out.println( String.format("%.2f",kg_weight) + " kilogram = " + String.format("%.2f", pound_weight) + " pounds");

    }
}
