I keep getting the error

' treehouse:~/workspace$ javac Example.java
./PezDispenser.java:31: error: reached end of file while parsing
}
^ Example.java:19: error: cannot find symbol
while (dispense.dispense()) {
^
symbol: variable dispense
location: class Example Example.java:22: error: cannot find symbol
if (dispense.isEmpty()){
^
symbol: variable dispense
location: class Example
3 errors '

My code

'''public class Example {

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

if (dispenser.isEmpty()){ System.out.println("The Dispenser is empty"); } System.out.println("Loading..."); dispenser.load();

  if (!dispenser.isEmpty()){
    System.out.println("It is no longer empty");}

while (dispense.dispense()) { System.out.println("Chomp!"); } if (dispense.isEmpty()){ System.out.println("You ate all the pez"); } }
} '''

In the while loop, dispense.dispense() should be dispenser.dispense(). Also, in your last if statement, dispense.isEmpty() should be dispenser.isEmpty().

Make sure you have the right number of closing braces: }

If you still get that error post your code please. Put three backticks, `, followed by java as the line right before the first line of code. Then put three backticks on its own line right after the last line of code.

Hey David.

Your code seems fine and does compile for me with no errors. I'm not sure why you are receiving an error. Weird.

My only suggestion is to select all the code in your work space and delete it. Make sure all white space is deleted (If this is the only code you have in the particular file in workspaces, just delete the file and make a new one). Then copy and paste the code you posted above back into the workspace and see if that loses the error. It may just be a glitch in the Workspace.

I'm not sure, but everything you have seems to work fine.

:dizzy:

Hi David - Did you get it to work? I just tried the code you pasted above and it compiled and ran fine. Let me know if you're still getting an error.

Hey guys thank you for you time and answers I fixed the problem, I felt that silly about it that I wasn't going to post but I will just in case others happen to have a brain fart and do the same. I was working on the Example file but the error was in the Dispenser file and wouldn't run because of that.
