Java Programming for Beginners: From Introduction To Your First Java Project

Concepts: Teach how to create a new class (subclass) based on an existing one (superclass), inheriting its attributes and methods. Introduce the extends keyword and method overriding.

Code example:

class Labrador extends Dog {
   public Labrador(String name, int age) {
      super(name, age);
}

// Overriding the bark method
@Override
void bark() {
   System.out.println(“Labrador bark!”);
   }
}

Quiz: Identify correct inheritance syntax and determine the output of code that uses method overriding.
