In disconnected architecture, class names should reflect the entities or objects they represent.
Class names should be meaningful and descriptive.
They should follow naming conventions, such as PascalCase or camelCase.
Avoid using abbreviations or acronyms that may not be easily understood.
Consider using domain-specific terminology to make the class names more intuitive.
Examples: Customer, Order, Product, Employee
Signature of multicast delegate
A multicast delegate is a delegate that can have multiple methods assigned to it
The signature of a multicast delegate is the same as that of a regular delegate
The signature includes the return type, name, and parameters of the delegate
Delegates are used to create references to methods and pass them as arguments to other methods.
Delegates allow for loose coupling between objects
Delegates can be used to implement callbacks and event handlers
Delegates can be used to implement the observer pattern
Delegates can be used to implement the command pattern
Delegates can be used to implement the strategy pattern

Functional interfaces are interfaces with a single abstract method, used for lambda expressions.
Streams provide a way to work with collections of objects in a functional style.
Default methods in interfaces ...
Interfaces in Java are implemented using the 'implements' keyword, allowing classes to provide specific implementations for methods defined in the interface.
Interfaces in Java define a contract for classes to implement, specifying method signatures without implementations.
A class can implement multiple interfaces by separating them with commas.
Classes implementing an interface must provide concrete implementations for ...
Stream API in Java provides a way to process collections of objects in a functional style.
Stream API allows for functional-style operations on collections like map, filter, reduce, etc.
It supports lazy evaluation, meaning operations are only performed when needed.
Streams can be sequential or parallel, depending on the source and operations used.
Spring Boot simplifies the setup and development of Spring applications by providing a convention-over-configuration approach.
Spring Boot eliminates the need for XML configuration by using annotations and sensible defaults.
It includes embedded servers like Tomcat, Jetty, or Undertow, making it easy to deploy standalone applications.
Auto-configuration feature reduces the amount of boilerplate code needed to set up a Spr...
