    Default Cannot seem to get this working

    So I searched the forums and the net and have to admit I'm hesitant of using a forum for answers but frankly I'm running out of idea's here. I picked up Sams Teach yourself Java 6 in 21 days and I am trying to get the blasted thing set up. Originally it was giving me a error "cannot find symbol" (2 errors) when I attempted to compile it. I changed from using Notepad to using ViM to write the code out again, now I have only 1 error. it reads as follows

    VolcanoApplication.java:16: cannot find symbol
    symbol : method checkTemperature()
    Location: class VolcanoRobot
    dante.checkTemperature();
    -------^
    1 error

    It seems to hate that period....
    Some quick background----
    I am new to programming in Java
    I am running Windows 7 Pro
    I have already set PATH in my enviroment variables and running jdk version 6
    Both .java files are in the same directory.

    I have attached Volcano Applications code below

    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();
    	}
    }

    Here is the VolcanoRobot.java aswell

    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);
    	}
    }

    void checktemperature() , notice the not capitalized "t"

    dante.checkTemperature() , notice the capitalized "T"


    Woot?

    Edit: What I mean ofc, is that poor dante would have more luck with finding the "checktemperature()" method
