What is wrong with this? (trying to follow tutorials)

I'm trying to follow the tutorials so I just made something up. I saved the file as heater.java

I did the javac heater.java thing (I have tried different letter cases)

Then I typed java Heater (using different cases again)

I keep getting this error:
Exception in thread "main" java.lang.NoSuchMethodError: main.

This is the code, which basically follows the bicycle tutorial, I tried copying and pasting that, but still had the same problem.

class Heater {

int power = 0;
int steam = 0;

void changePower(int newValue) {
power = newValue;
}

void changeSteam(int newValue) {
steam = newValue;
}

void printStates() {
System.out.println("power:"+power+" steam:"+steam);
}
}

class Heater1 {
public static void main(String[] args) {

//create two heaters
Heater heat1 = new Heater();
Heater heat2 = new Heater();

//methods for the two heaters
heat1.changePower(3);
heat1.changeSteam(20);
heat1.printStates();

heat2.changePower(1);
heat2.changeSteam(3);
heat2.printStates();

}
}

BTW the tabs are where they should be.

Nothing wrong with the code. It was what he was typing into the console that caused the problem.
