Question

I want to use/call a method inside EdumateSuperClass that I created in Navigation class. Is that possible? Anything I tried didn’t work.

public abstract class EdumateSuperClass extends ScriptSuperClass

public abstract class Navigation extends EdumateSuperClass

• super.clickNewButton(); –> The method clickNewButton() is undefined for the type ScriptSuperClass

PS Please update the title if necessary. Not sure if I used the right terminology.

Answer 1

You have to declare the method as abstract in the using class (or its parent classes), and implement it in the child class:

public abstract class EdumateSuperClass {
    protected abstract void childMethod(String message);

    public void callChildMethod() {
        childMethod("hello");
    }
}

public abstract class Navigation extends EdumateSuperClass {
    protected void childMethod(String message) {
        System.out.println(message);
    }
}
