method in subclass not seeing method in abstract superclass

[Bud Tippins]

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

public static void main(String[] args) {
        System.out.println("I'm gonna call apple");
        Apple myApple = new Apple();
        myApple.outPut();
        myApple.sayFruit();
    }

}


class Apple extends Fruit {
    String appleSay = "I'm an apple";
    void outPut() {
    System.out.println(appleSay);
    }

}

In the abstract Fruit class I have:

public abstract class Fruit {
    void sayFruit() {
        System.out.println("I'm a fruit");
    }
}

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"

public class Tester
{
  public static void main(String[] args) 
  {
          System.out.println("I'm gonna call apple");
          Apple myApple = new Apple();
          myApple.outPut();
          myApple.sayFruit();
  }
}

class Apple extends Fruit {
    String appleSay = "I'm an apple";
    void outPut() {
    System.out.println(appleSay);
    }

}

and this in another file called Fruit.java

public abstract class Fruit {
    void sayFruit() {
        System.out.println("I'm a fruit");
    }
}

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

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.

[Bud Tippins]

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

package abstractclasses;

import food.Fruit;
public class Main {

    public static void main(String[] args) {
        System.out.println("I'm gonna call apple");
        Apple myApple = new Apple();
        myApple.outPut();
        myApple.sayFruit();
    }

}


class Apple extends Fruit {
    String appleSay = "I'm an apple";
    void outPut() {
    System.out.println(appleSay);
    }

}

This is in fruit.java:

package food;

public abstract class Fruit {
    void sayFruit() {
        System.out.println("I'm a fruit");
    }
}

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.

[Bud Tippins]

thank you. That worked.
