Hi, I'm completely brand new to Java, and have been learning from the books.

In one of the book exercises, I was supposed to copy and paste two scripts (VolcanoApplication.java & VolcanoRobot.java) and compile VolcanoApplication.java so I could run the program. Unfortunately, whenever try to compile VolcanoApplication.java in Cmd (Javac C:\ etc.), no class file is created and I get this error message:



I copied the code exactly from the book:

VolcanoApplication.java:

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();
    }
}

VolcanoRobot.java

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);
       }
    }

I'm sure there must be a simple fix for this, but as I'm completely new to Java, I have no idea what to do. Please help!

Thanks
