Question

Write a Java program by String Class that asks the user to enter distance in Kilometers. The program then computes the distance in Miles using the following formula: Miles = 0.621371 × Kilometers The program should display the distance in Kilometers and Miles as follows: Distance: 100 Kilometers = 62.1371 Miles

A properly documented source code (.java files) (Do not need to add a comment in each line, but you must explain the code appropriately). At the start of the code, identify the student number and name, and also state the question number and date.  

Explanation / Answer

import java.util.Scanner;

public class KmtoMilesDemo {
public static void main(String[] args) {
//... Declare variables.
String KilometerStr; //String that holds kilometers
double kilometers; // Distance in kilometers.
double miles; // Distance in miles.
  
//... Input distance in kilometers.
Scanner in = new Scanner(System.in);

System.out.println("Enter distance in kilometers:");
KilometerStr = in.nextLine();
System.out.println("You entered distance "+KilometerStr);
kilometers = Double.parseDouble(KilometerStr); //cast in double   

//conversion by given formula
miles = kilometers * 0.621371;

//print converted distance in miles
System.out.printf("Distance: %fKilometers = %fMiles",kilometers, miles);
}
}
