An error might help.

The CarRental class obviously has no constructor taking no arguments (also known as a "default constructor").There, I can tell that without even seeing your code, since my crystall ball is once again functioning.

This IS the error...symbol : constructor CarRental()location: class CarRentalCarRental cr1 = new CarRental();

It's telling you exactly what's wrong. You're trying to invoke a CarRental constructor that takes no arguments, but CarRental has no such constructor.

I thought that this was my constructor?

class CarRental

{

protected String customerName, location, carSize;

protected double costPerDay;

protected byte daysRented;

public CarRental(String custName, String loc, String cSize, byte dRented)

{

custName = customerName;

loc = location;

cSize = carSize;

dRented = daysRented;

}

I see a constructor there taking four arguments. So don't you think you'd better pass that many arguments when you try to invoke the constructor?

Yet you did this instead:

> CarRental cr1 = new CarRental();

No arguments passed to it. See now?

I dont understand...im sorry im new to java

oooh okay...so it would look something like...CarRental cr = new CarRental(customerName, location, carSize, daysRented)?

Yes, assuming you have customerName, etc declared as variables and which have the right values to pass, of course.

Whoa, and all these are backwards in the constructor:

custName = customerName;

loc = location;

cSize = carSize;

dRented = daysRented;

You need to do those in the other order:

customerName = custName; // set the customerName member variable equal to the argument

etc.

Yes, that is a constructor, but it takes 4 arguments and you are trying to create an object, while passing 0 arguments to the constructor. That wont work.

do I have to initialize each variable too?

> do I have to initialize each variable too?I can see that we're having to guess a little too much about what you mean to pull things out of you for context, so I'm going to have to walk away. Good luck.

Now I am getting an error saying that it "cannot find symbol" and then points to all the arguments in the class

Then curse the man who invented the language: curse James Gosling, vice-president of Sun Microsystems Inc. of Santa Clara, California!
