I have the following code in the main.java file.



In the abstract Fruit class I have:



Why am I getting an errot on the "myApple.sayFruit();". Isn't the sayFruit() method visible to main?

Thank you.

is that all your code? Your main() method has to be inside a class, which it does not appear to be from what you posted. I put this in a file called "Tester.java"

and this in another file called Fruit.java

I compiled both files, and it ran just fine:

C:\slop>java Tester
I'm gonna call apple
I'm an apple
I'm a fruit



There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors

You've defined your sayFruit() method with the package-private modifier (i.e. you've not used an access modifier like public, private or protected for it) so visibility for it is classes in the same package as your Apple class. Sub classes cannot see it unless they are in the same package too.

Sorry. Here is the complete code in Main.java:



This is in fruit.java:



Thank you for your help

That's because you haven't added an access modifier to sayFruit. And by default it gets package access, which means that it's only accessible to classes in the same package - which doesn't include Main. Add public and it will work.

Edit: sorry - missed that Paul had already said that.
