Super to Access Superclass Members
super to Access Superclass Members In Java, the super keyword refers to the immediate parent class of a given object. It is used to access members (fields, methods, and constructors) of the parent class from the child class. Key Uses of super: Accessing Superclass Methods: It is used to call a method of the superclass when the subclass has overridden that method. Accessing Superclass Constructor: It is used to call the constructor of the superclass from the subclass. Accessing Superclass Fields: It allows access to the fields of the superclass. Example 1: Using super to call a superclass method class Animal { void eat() { System.out.println("Animal is eating..."); } } class Dog extends Animal { void eat() { super.eat(); // Call the eat() method of the parent class Animal System.out.println("Dog is eating..."); } } public class Main { public static void main(String[] args) { Dog dog = new Dog(); dog.eat(); // Output will be: Animal is eating... Dog is eating... } } Example 2: Using super to call a superclass constructor class Animal { Animal() { System.out.println("Animal constructor"); } } class Dog extends Animal { Dog() { super(); // Call the constructor of the parent class Animal System.out.println("Dog constructor"); } } public class Main { public static void main(String[] args) { Dog dog = new Dog(); // Output will be: Animal constructor Dog constructor } } Example 3: Using super to access a superclass field class Animal { String name = "Animal"; } class Dog extends Animal { String name = "Dog"; void display() { System.out.println("Name from Dog class: " + name); System.out.println("Name from Animal class: " + super.name); // Access the name from Animal class } } public class Main { public static void main(String[] args) { Dog dog = new Dog(); dog.display(); // Output will be: Name from Dog class: Dog Name from Animal class: Animal } } 🔗 Related Notes Access Modifiers Method Overloading Static Keyword Inheritance Types of Inheritance Abstract Classes
