Compile errors but seems correct.

[syronix]

This is my second post in the past couple of hours about a compiler error, but that was my fault. This time I'm almost 100% i followed the steps correctly in the tutorial and this simple class should compile just fine. I've listed the errors as comments.

import java.util.Scanner;

class VersatileSnitSoft {

       public static void main(String args[]) {
              Scanner myScanner - new Scanner(System.in); 
             //error ';' expected line 6 ^
              double amount;
             //Now here I've set the keyword double to the variablename amount
             
            System.out.print("What's the price of a CD-ROM? ");
            amount - myScanner.nextDouble();
            //error: not a statement line 10 ^
            amount - amount + 25.00;
            //error: not a statement line 11 ^

            System.out.print("We will bill $");
            System.out.print(amount);
            System.out.println(" to your credit card.");
       }
}

any help would be greatly appreciated thank you for your time.
I really just want to know why my amount - myScanner.nextDouble(); isnt' a statement and how do I make it a statement.
I just started with variables and I by no means am good at this yet.

These should be assignments, not subtractions.
Java is smart, it won't let you perform operations on something that would provide a distinct result without actually assigning it to something. i++ is fine, but i + 1 would require an assignment.

So are you saying I need to assign the variable to something for the class to call?

[Fou-Lu]

No I'm saying these need to be assignments for the variables themselves. This class will run standalone since it already has a main method constructed. Unless I misunderstand what you mean?

This: Scanner myScanner - new Scanner(System.in); should be Scanner myScanner = new Scanner(System.in); , and same for the assignments below with the amount variable.

Thank you so much that fixed my compile errors, Honestly i thought it should look like this but I didn't want to differ from my instruction just in case i was wrong. Again thanks.
