Java Code:

//This class demonstrates the Distance.java class
//Branden Sullivan

import java.util.Scanner;

public class DistanceDemo
 {
 	public static void main(String[] args)
	 {
	 	//allows the user to type in the amount of miles
	 	Scanner keyboard = new Scanner (System.in);
				
		//variables are declared here
		double newMiles;
		
		Distance problem = new Distance("dist");
		
		//aquiring the miles
		System.out.print("How many miles?   ");
		newMiles = keyboard.nextDouble();
		
		//telling the user if they have entered a invalid number
		if(newMiles < 0){
			newMiles = 0;
			System.out.println("You have entered an invalid number and the miles will be set to zero.");
		}
		if(newMiles > 0){
			System.out.println("There are " + problem.convertToFeet() + " feet in " + problem.getMiles() + " miles");
		}
		
		
		//acquiring another set of miles
		System.out.print("Enter another number of miles to conver to feet:     ");
		newMiles = keyboard.nextDouble();
		
		//telling the user if they have entered a invalid number
		if(newMiles < 0){
			newMiles = 0;
			System.out.println("You have entered an invalid number and the miles will be set to zero.");
	 	}
		if(newMiles > 0){
			System.out.println("There are " + problem.convertToFeet() + " feet in " + problem.getMiles() + " miles");
		}
		
		
		
	 }
 }

this is what i have so far. this worksheet says to call for the mutator method to change the number of miles in the distance object and to call the accessor method and the conversion method to display the information with the appropriate labels

this is my other class

Java Code:

public class Distance
 {
 	//variables are declared here
	private double Miles;
	private double convertToFeet;
	
	public Distance(String dist){
	}
	
	public void setMiles(double newMiles){
		Miles = newMiles;
	}
	
	public double getMiles(){
		return Miles;
	}
	
	public double convertToFeet(){
		convertToFeet = Miles * 5280;
		return convertToFeet;
	}
 
 }
