Question

Create a program named CableCar.java:

Use the following header and instance variables:

public class CableCar {

// instance variables private int length;

private int passengers;

private String street;

Write the following methods:

a) Default constructor. Initialize the String variables to the empty String and numeric variables to zero.

b) Another constructor. Accept 3 parameters, in order, for length, passengers, and street. Call the mutators from within this constructor. (There should not be any assignment statements in this constructor.)

c) 3 Accessors: one for each instance variable.

d) 3 Mutators: one for each instance variable. Mutators for length and passengers should perform data validation to insure that only positive values are stored in those variables.

e) toString method: return a String with this format "street Street Cable Car length feet long Capacity: passengers passengers"

I've tried to get this, but the code doesn't compile and I have no idea why. I'm hoping if someone can show me I can fix my mistake. So any help would be greatly appreciated. Thank you.

TESTING THE CLASS

*********************************************************************

********************************************************************/

public class CableCarTest
{
public static void main(String[] args)
{
CableCar carrito= new CableCar();
System.out.println(carrito.toString());
CableCar carrote =new CableCar (15,20,"evergreen");
