Why do I keep getting an invalid flag error?

When I try to compile and run I get this message:

javac: invalid flag: %%

Usage: javac [options] [source files]

use -help for a list of possible options

But with arrow brackets instead of regular brackets. Sorry, I don't know how to input it here so it shows up properly!

My code is the exact same, as far as I can see, as the code in the video :(

public class Example {

    public static void main(String[] args) {
        // Your amazing code goes here...
        System.out.println("We are making a new Pez Dispenser.");
        PezDispenser dispenser = new PezDispenser();
        System.out.printf("The dispenser character is %s\n",
                          dispenser.mCharacterName);
    }
}

Oy. I figured it out. It's so dumb, I'm afraid to say it. I put %% instead of && when I was running the command. Noob apologies.

Haha. It happens. Good luck with future programming!

It would help if you posted your code between three ticks.

code here 

the ` is located just below the escape key, at least on windows.

I did some research, and an invalid flag error is based on the command you are putting into the console. Make sure there are no spaces in the file and the file name is spelled correctly.

None that I can find :/ Everything seems to be spelled correctly.
