Cannot find symbol

I am having issues with Jshell while the isEmpty method is executed. I created a new pez dispenser called "Yoda" but then when I tried to execute that method is displaying this error message : jshell> pd.isEmpty();
| Error:
| cannot find symbol
| symbol: method isEmpty()
| pd.isEmpty();
| ^--------^

My method is the following: public boolean isEmpty(){ return pezCount == 0;

I don't know where the issue is, what it could be?

i don't have any idea how it looks your code but "can't find symbol" mean that the function your try to call is unknown

ex: Object shape;

shape.isEmpt(); this will trow an error because isempty is not exit till you instantiate the Object with new key

For anyone else reading this. If you get this error, you need to be sure that you go back into your class again in jshell by simply typing /open PezDispenser.java and then re-running pd.isEmpty();
