Try running javac PezDispenser.java and make sure it compiles.

When I do this I get:

    javac PezDispenser.java;

    javac PezDispenser.java;

EDIT: nevermind found my error, had a typo in one of my mPezCounts and the above error was from trying to do "javac PezDispenser.java" in java-repl and not out of it in the normal console.

Craig Dennis U mean to say first i have to compile PezDispenser.java file and then use the :load command , but when we activate the repl we dont compile we just save the file n load. Its confusing !

No I mean it seems that if the :load command isn't working, it might be a compile error that it isn't showing up in the REPL. Running javac will let you see the error (if there is one).

When I ran the javac command outside the java-repl, i was able to see my misspelling and undefined variables (more misspelling). After running javac for the third time, I received no errors. I went back into repl command line and typed in PezDispenser pd = new PezDispenser("Yoda"); and it worked. No java.util.NoSuchElementException error.

Sorry, not in the REPL on the command line. Trying to see if there is an error in the PezDispenser.java file.

I had this same error, I hadn't removed the = from the public void we created and called return on. I removed the = after return and it worked great!

I was getting this exception thrown because I wasn't loading the .class file. It immediately corrected itself once I typed: ": load PezDispenser.class".

I had this problem for a while, and only when I compiled it did I realize there was an error with isEmpty. The return type is boolean in the method signature, and had return mPezCount = 0 inside the { } which I guess is returning an integer. Everything was fixed once I added another equal sign, so like mPezCount == 0

I was having this error as well. I think the problem was that I didn't compile the code before entering the repl. Once I did compile it with javac PezDispenser.java I found that I had an error (I capitalized the "p" in "public"). After correcting my error, everything worked!
