Spring Boot - Inversion of Control and Dependency Injection

Given this Spring bean code snippet, what will be printed when the bean is initialized?

@Component
public class MyBean {
  @PostConstruct
  public void init() {
    System.out.println("Bean initialized");
  }
}

ABean destroyed

BNo output

CBean initialized

DCompilation error

Step-by-Step Solution

Solution:

Step 1: Understand @PostConstruct behavior
The method annotated with @PostConstruct runs after the bean is created and properties set, printing "Bean initialized".
Step 2: Check output possibilities
Since the method prints a message on init, output will be "Bean initialized". No errors or destruction messages occur here.
Final Answer:
Bean initialized -> Option C
Quick Check:
@PostConstruct prints "Bean initialized" [OK]

Quick Trick: PostConstruct method runs once after bean creation [OK]
