Question

• Write a convertToMetric class that has the following field:
  • standard - holds a double, standard length value in feet.
• The class should have the following methods:
  • Constructor - that accepts a length in feet (as a double) and stores it in the standard field.
  • setStandard - accepts a standard length in feet and stores it in standard.
  • getStandard - returns the value of the standard field, as a length in feet, no conversion required.
  • getMeters - returns the value of the standard field converted to meters.
  • getCentimeters - returns the value of the standard field converted to centimeters
• A second class will be created and used to test the new object class. This, executable class, is to instantiate an object of 'convertToMetric' type. Then it will allow the user to use keyboard input to input a value for standard. That value will then be converted to meters and centimeters, and displayed.
• Make sure that your output (or display) is user-friendly or easy to read and understand. You should display the length in feet, length in meters and length in centimeters.

CODE as plain text:

import java.util.Scanner;

public class ConvertToMetric {
    double standard;

    public double getStandard() {
        return standard;
    }

    public ConvertToMetric(double standard) {
        this.standard = standard;
    }

    public double getMeters() {
        return this.standard * 0.3048; // 1 foot is 0.3048m
    }

    public double getCentiMeters() {
        return this.standard * 30.48; // 1 foot is 30.48cm
    }


}

class TestingMetric {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in); // creating object of scanner class to take the input from user from keyboard
        System.out.println("Enter standard value (in feet)");
        double input = sc.nextDouble();
        sc.close(); // close the Scanner object. No longer we want to take input from user now
        ConvertToMetric c = new ConvertToMetric(input);
        double met = c.getMeters();
        double cms = c.getCentiMeters();
        System.out.println(input + " feet in meters is " + met + " and in centimeters is " + cms);
    }
