Module 26: Super Keyword

🧭 What is the super Keyword?

The super keyword in Java is a reference variable used to refer to the immediate parent class object. It is primarily used in inheritance scenarios to access the parent class members.

✨ Use Cases of super Keyword

• To call the parent class constructor
• To access parent class methods that are overridden
• To access parent class variables when they are hidden

📘 Example: Using super

                    class Animal {
                      String color = "white";
                    
                      void eat() {
                        System.out.println("Animal eats food");
                      }
                    }
                    
                    class Dog extends Animal {
                      String color = "black";
                    
                      void printColor() {
                        System.out.println(super.color);  // accesses parent class variable
                      }
                    
                      void eat() {
                        System.out.println("Dog eats bones");
                      }
                    
                      void work() {
                        super.eat();  // calls parent class method
                      }
                    }
                    
                    public class Main {
                      public static void main(String[] args) {
                        Dog d = new Dog();
                        d.printColor();  // Output: white
                        d.work();        // Output: Animal eats food
                      }
                    }
