2.Default keyword is used in the context of interfaces in Java. It defines a default implementation of a method in an interface. This allows the interface to provide a default implementation for a method, which can be overridden by implementing classes if needed. Here's an example of a defa...
Java doesn’t support multiple-class inheritance. Subclasses of an abstract class in Java must implement all the abstract methods unless the subclass is also abstract. In interfaces, all methods are inherently abstract, except for static or default methods, which were introduced in Java 8. Java ...
