Qu'est-ce que @override en Java, comment l'implémenter dans le programme

Par exemple, un programme Java simple pour illustrer le remplacement de méthode en java:

// Base Class 
class Parent { 
    void show() 
    { 
        System.out.println("Parent's show()"); 
    } 
} 
  
// Inherited class 
class Child extends Parent { 
    // This method overrides show() of Parent 
    @Override
    void show() 
    { 
        System.out.println("Child's show()"); 
    } 
} 
  
// Driver class 
class Main { 
    public static void main(String[] args) 
    { 
        // If a Parent type reference refers 
        // to a Parent object, then Parent's 
        // show is called 
        Parent obj1 = new Parent(); 
        obj1.show(); 
  
        // If a Parent type reference refers 
        // to a Child object Child's show() 
        // is called. This is called RUN TIME 
        // POLYMORPHISM. 
        Parent obj2 = new Child(); 
        obj2.show(); 
    } 
}
