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.

Submit convertToMetric.java and testConvertToMetric.java as attachments under Assignment Submission.

if you could provide an idiot proof walkthrough i would appreciate it. im having problems with textpad compiling and running the programs. Thank you

Answer 1

/*
* Java program that prompts the user to enter the length value for feet
* and then display the meters and centimeters of the corresponding feet
* on the java console window.
* */
//testConvertToMetric.java
import java.util.Scanner;
public class testConvertToMetric
{
   public static void main(String[] args)
   {
       //Create a Scanner class object
       Scanner scan=new Scanner(System.in);
       System.out.print("Enter standard value(in feet) : ");
       //read feet value from console
       double feet=Double.parseDouble(scan.nextLine());
      
       //Create an object of convertToMetric class
       convertToMetric obj=new convertToMetric(feet);

   }
