Extending multiple classes will cause Java to throw an error during compile time: class Animal { boolean alive = true; } class Poodle extends Dog, Animal { } // ERROR: Class cannot extend multiple classes When
Extending Two Classes Using Composition Composition in Java is vital for extending two classes as it avoids the complexities of multiple inheritance. It fosters code flexibility, promotes encapsulation, and prevents the diamond problem. By creating relationships between classes through composition, developers...

Why Java does not support multiple inheritance of classes? In one line, the answer to this question is to prevent ambiguity. In the above figure, we can see that Class C extends both Class A and Class B. Suppose both classes have the same method display(). In this case, the Java comp...
The concept of multiple inheritance is implemented in Java by (A) extending two or more classes (B) extending one class and implementing one or more interfaces (C) implementing two or more interfaces (D) all of these• (A) • (B) & (C)...
See the JavaServer Faces API documentation to find out what the other component classes implement. You can also make your component explicitly implement a behavioral interface that it doesn't already by virtue of extending a particular standard component. For example, if you have a component that...
Parent obj = new Child();obj.performAction(); // Calls the parent's version of performAction() 3. Bridging Generations with Constructors: Class hierarchies can span multiple generations of parent and child classes. Using the “super” keyword in constructors, you can establish a smooth chain...

The interface is shared across multiple MarkLogic client APIs, so you can use the same extensions with the Java Client API, Node.js Client API, and the REST Client API. For the interface definition, authoring guidelines, and example implementations, see Extending the REST API in the REST ...
