Let’s break them down into types to understand their roles and how to handle them effectively! What are the Different Types of Exceptions in Java? The exception hierarchy in Java is divided into three main types: checked, unchecked, and custom. Each plays a distinct role in error management...

Some languages (e.g., Java) can use named interfaces instead of classes to introduce user-defined types. Most object-oriented programming languages provide primitive data types (e.g., integer) that are not defined as classes. • An object can have different types, and objects from different...

In Scala programming language everything is an object. Even data types are treated as objects in Scala and have some method that performs operations of the data stored by them. So, all the data types, functions/methods, classes you define have a type and the type is defined in the type ...

Array types (boolean[],Object[],StackImpl[]) implicitly augment the inheritance hierarchy. The inheritance hierarchy depicte...
Null is a subtype of all reference types (AnyRef), but not of value types (AnyVal). It represents the absence of a value. It is similar to null in Java. However, its usage is generally discouraged in favor of safer alternatives.
