Monolithic architecture sample code in java:

Here is a simplified example of a monolithic architecture in Java:

// Monolithic application with multiple components public class MonolithicApp { public static void main(String[] args) { // Business logic UserService userService = new UserService(); String message = userService.getUserMessage(123); System.out.println(message); } } class UserService { public String getUserMessage(int userId) { // Database access and business logic String userName = UserRepository.getUserName(userId); return "Hello, " + userName + "!"; } } class UserRepository { public static String getUserName(int userId) { // Database query return "John Doe"; } }

In this example, the entire application is structured as a monolithic architecture. The MonolithicApp class represents the entry point of the application. It directly calls the getUserMessage() method of the UserService class, which internally accesses the UserRepository to retrieve user information from the database.

All the components, including the user interface, business logic, and data access layers, are tightly coupled within the monolithic application. They are developed, deployed, and scaled together as a single unit.

Note that this example is simplified for illustration purposes and may not reflect the complexity of real-world monolithic applications. In practice, monolithic applications can consist of multiple classes, packages, and dependencies, providing a self-contained solution within a single codebase.
