Apr 8, 2023 · In this article, we will discuss How to Implement Multiple Inheritance by Using Interfaces in Java. Syntax: Class super {-----} class sub1 Extends super {-----} class sub2 Extend sub1 {-----} Implementation. Multiple inheritances can be achieved through the use of interfaces.

Dec 26, 2024 · Multiple Inheritance is a feature of an object-oriented concept, where a class can inherit properties of more than one parent class. The problem occurs when there exist methods with the same signature in both the superclasses and subclass.

Multiple inheritance by interface occurs if a class implements multiple interfaces or also if an interface itself extends multiple interfaces. A program that demonstrates multiple inheritance by interface in Java is given as follows: Example Live Demo

Dec 26, 2024 · Java supports three types of inheritance in Java: single-level, multilevel, and hierarchical inheritance in the case of classes to avoid ambiguity. In Java programming, multiple and hybrid inheritance is supported through the interface only. 1. Single Inheritance. When a class inherits another class, it is known as a single inheritance. 2.

Feb 14, 2025 · In this article, we will deep-dive into the concept of multiple inheritance in Java, building upon previous tutorials on inheritance, interface, and composition in Java. Inheritance in Java is implemented using the extends keyword. Here’s an example: dog.makeSound(); // Inherited method . dog.bark(); // Child class method } }

Jan 22, 2020 · Yes, it is possible. This is the catch: java does not support multiple inheritance, i.e. class cannot extend more than one class. However class can implement multiple interfaces.

Sep 10, 2024 · However, Java offers a method for achieving multiple inheritances through interfaces, enabling a class to implement many interfaces. We will examine the idea of multiple inheritance in Java, how it is implemented using interfaces, and …

Jan 4, 2023 · In multiple inheritance, a child class can inherit the behavior from more than one parent classes. Note that a Java class can implement multiple interfaces, but an interface does not define concrete behavior rather, interfaces are used for defining the contracts only.

Jan 20, 2015 · This answer is outdated: Java 8 allows multiple inheritance of method implementations in interfaces. An interface can extend one or more other interfaces. You can also implement more than one interface in your classes. It is legal because interface is only contract - there is no implementation.

Aug 7, 2017 · In the above class diagram, interface B inherits from interface A. Both have a default method print () with the same signature. Class C implements both interfaces A & B.
