Question

Java COSC 237 Problem: You are to develop a program that allows a user to convert lengths in the metric system (i.e., meters/centimeters) to the Imperial system (i.e., feet/inches) AND convert lengths in the Imperial system to the metric system.

Specifications

• Input may be given with or without decimal places.

• Error checking for invalid input is not required.

• The results are to be displayed with two decimal places of precision. (For example, 2 meters, 25 centimeters (225 centimeters) is equal to 7 feet, 4.58 inches.)

• The program should allow the user to continue to convert values until they choose to quit

• While the creation of your own classes (objects) is not expected, static methods (functions) should be utilized

import java.util.*;

class ConversionSystem
{
public static void main (String[] args) throws IOException
{
String choice; //define choice to get user input
Scanner scan = new Scanner(System.in);
System.out.println("Please enter inputs for Conversion, if you want to stop enter 'quit'" );
choice = scan.nextLine(); //scan the input
while(!(choice.equals("quit"))) //take input until user enters quit
{
String[] inputStrings = choice.split(" "); //split the user input ex: "2 meters" to "2","meters"
Double length = Double.parseDouble(inputStrings[0]);   //convert first argument (ex: "2") to double
String converstionSystem = inputStrings[1]; //separate Conversion system from the user input ex:"meters"

if(converstionSystem.equals("meters")) //convert from meters to feet
{
Double result = length/0.305; //formula to convert
String resultFormated = String.format("%.2f", result); //format two decimal places of precision
System.out.println(resultFormated+"feet"); //print the output
}

else if(converstionSystem.equals("centimeters")) //convert from centimeters to inches
{
Double result = length*0.394; //formula to convert
