Here SubClassB inherited the methodfoo()fromSuperClassA. Polymorphism:Polymorphism means taking many forms, where ‘poly’ means many and 'morph' means forms. Polymorphism allows you define one interface or method and have multiple implementations. In Java, there are two types of polymorphism: comp...

The huge benefit of this is that refactorings become much simpler as in languages where every function or method might mutate data. Thus it will also be more easy to reason about a given piece of code.Of course this also makes programming of concurrent operations much easier. With a shared...
Explain overloading a method in java. In java, under what circumstances should an interface be used instead of an abstract class? What is the concept of reusability, and how do you design for reusability? Provide an example. (a) Explain the pigeonhole principle. (b) Give an example that ...
Both programming languages support operator overloading. But Scala’s operator overloading is much better as compared to Kotin. Pattern Matching: Again Both Support pattern matching but for Scala, the match method takes the bout which can match almost every data type available in the code. ...
