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...
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 you need to extend two or more classes in Java, you need to refactor the cl...
2) Multiple Inheritance “Multiple Inheritance” refers to the concept of one class extending (Or inherits) more than one base class. The inheritance we learnt earlier had the concept of one base class or parent. The problem with “multiple inheritance” is that the derived class will have to...
Enhances the Java programming language by extending pattern matching to destructure instances of record classes, enabling more sophisticated data queries. Add nested patterns, enabling more composable data queries. Related to: [JDK 19] JEP 405: Record Patterns (Preview) [JDK 20] JEP 432: Record ...
In the world of programming, multithreading is a powerful technique that allows an application to perform multiple tasks simultaneously. It’s like having multiple workers in a factory, each handling a different task at the same time, making the process faster and more efficient. Without multithread...

Create a Thread by Extending a Thread Class The second way to create a thread is to create a new class that extends Thread class using the following two simple steps. This approach provides more flexibility in handling multiple threads created using available methods in Thread class. ...
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...
