It told me to make a file called VolcanoRobot.Java and put this in it: [code]class VolcanoRobot { String status; int speed; float temperature; void checkTemperature() { if (temperature > 660) { status = "returning home"; speed = 5; } } void showAttributes() { System.out.println("status: " + status); System.out.println("Speed: " + speed); System.out.println("Temperature: " + temperature); } }[/code] And then it says to make another file called VolcanoApplication.Java which has this inside: [code]class VolcanoApplication {    public static void main(String[] arguments) {        VolcanoRobot dante = new VolcanoRobot();        dante.status = "exploring";        dante.speed = 2;        dante.temperature = 510;        dante.showAttributes();        System.out.println("Increasing speed to 3.");        dante.speed = 3;        dante.showAttributes();        System.out.println("Changing temperature to 670.");        dante.temperature = 670;        dante.showAttributes();        System.out.println("Checking the temperature.");        dante.checkTemperature();        dante.showAttributes();    } }[/code] When I try and compile the application, I get the following errors: [code]Ana:~ Ana$ javac desktop/Java/VolcanoApplication.Java desktop/Java/VolcanoApplication.Java:3: cannot find symbol symbol  : class VolcanoRobot location: class VolcanoApplication        VolcanoRobot dante = new VolcanoRobot();        ^ desktop/Java/VolcanoApplication.Java:3: cannot find symbol symbol  : class VolcanoRobot location: class VolcanoApplication        VolcanoRobot dante = new VolcanoRobot();                                 ^ 2 errors[/code] WHICH IS REALLY ANNOYING SINCE I DID EXACTLY WHAT THE BOOK SAID! I even copied the code off their website so I could make sure the problem was with the code, not something I'd done wrong... Anyway, since that didn't work, I then combined the two files which let me compile it without a problem but it wouldn't let me run the program... This is reeeeeeeeeallllllllllly annoying.
