Polymorphism
Learn how Java allows one interface or parent type to represent different object behaviors.
Java Code
Study the example and understand what each part does.
class Animal {
void sound() {
System.out.println("Animal sound");
}
}
class Dog extends Animal {
@Override
void sound() {
System.out.println("Dog barks");
}
}
public class Main {
public static void main(String[] args) {
Animal animal = new Dog();
animal.sound();
}
}Java code normally runs using the Java Development Kit on a computer, Android Studio or another Java development environment. This course page presents the code examples without pretending that the browser is running Java directly.
