Do you have experience working with the concept of Consumer in system development or integration?

In Java, a Consumer is a functional interface from the package java.util.function that accepts one input parameter and returns nothing. It is often used for data processing, for example, when working with streams or callbacks.

Example of using Consumer:

import java.util.function.Consumer;

public class ConsumerExample {
    public static void main(String[] args) {
        Consumer<String> printer = s -> System.out.println("Received: " + s);
        printer.accept("Test message");
    }
}

In system integration, the concept of Consumer is often found in message exchange patterns, where a Consumer is a component that receives and processes messages (e.g., from a queue or topic). This approach helps separate the sender (Producer) and receiver (Consumer), enabling asynchrony and scalability.
