  1. Nov 1, 2023 · The covariant method overriding approach, implemented in Java 5, helps to remove the client-side typecasting by enabling you to return a subtype of the overridden method's actual return type. Covariant Method overriding means that when overriding a method in the child class, the return type may vary. Before java 5 it was not allowed to override any

    • Only inherited methods can be overridden. Because overriding happens when a subclass re-implements a method inherited from a superclass, so only inherited methods can be overridden, that’s straightforward.
    • Final and static methods cannot be overridden. A final method means that it cannot be re-implemented by a subclass, thus it cannot be overridden.
    • The overriding method must have same argument list. Let’s see the following example: public class Animal { protected void eat(String food) { // animal eating code... } }
    • The overriding method must have same return type (or subtype). Suppose that a Foodclass has a subclass called DogFood, the following example shows a correct overriding
  2. Aug 10, 2021 · Method 1: Using a static method. This is the first way of preventing method overriding in the child class. If you make any method static then it becomes a class method and not an object method and hence it is not allowed to be overridden as they are resolved at compilation time and overridden methods are resolved at runtime. Java. import java.io.*;

  3. Mar 19, 2010 · Definitely, we cannot override static methods in Java. Because JVM resolves correct overridden method based upon the object at run-time by using dynamic binding in Java. However, the static method in Java is associated with Class rather than the object and resolved and bonded during compile time.

  4. Any method that is static cannot be used to override. The return type must have to be the same, or a subtype of the return type declared in the original overridden method in the parent class. If a method cannot be inherited, then it cannot be overridden.

  5. Jun 30, 2023 · An instance method cannot override a static method, and a static method cannot hide an instance method. For example, the following program has two compiler errors. In a subclass (or Derived Class), we can overload the methods inherited from the superclass.
