Thread: cannot find symbol error

Hi, I am new to java this semester and I am getting a cannot find symbol error(calculateCentimeters,calculateFeet,calculate Yards). I am struggling to fix this, any advice would help. It is the system.out.println lines that are wrong and I must have a return in this program. Thank you.

class inchesProgram{
 
    public static void main (String args[]){
 
        double inches = 1000.0;
 
	ItoC(inches);// method call //
	ItoF(inches);// method call //
	ItoY(inches);// method call //
 
	System.out.println("This is centimeters for 1000 inches: "+calculateCentimeters);
	System.out.println("This is feet for 1000 inches: "+calculateFeet);
	System.out.println("This is yards for 1000 inches: "+calculateYards);
	}
 
    static double ItoC(double inches){
		double calculateCentimeters;
		calculateCentimeters = inches*2.54;
		return calculateCentimeters;
	}
 
    static double ItoF(double inches){
		double calculateFeet;
		calculateFeet = inches/12;
		return calculateFeet;
	}
 
    static double ItoY(double inches){
		double calculateYards;
		calculateYards = inches/36;
		return calculateYards;
	}
}

When declaring a variable, you have to give it a type. I can't just say:

x = 7;

I have to tell Java what the heck x is:

int x = 7;

Same with Strings, Objects, doubles, whatever.

Yes, but you declared them inside the method, which means they're only available inside the method. Hint- You're returning a value from those methods, but you aren't doing anything with those values.

Those methods should almost definitely not be void.
