Which two statements are true regarding bean creation? (Choose two.)

Question

Options

• AA Spring bean can be explicitly created by annotating methods or fields by @Autowired.
• BA Spring bean can be implicitly created by annotating the class with @Component and using
• CA Spring bean can be implicitly created by annotating the class with @Bean and using the
• DA Spring bean can be explicitly created using @Bean annotated methods within a Spring
• EA Spring bean can be explicitly created by annotating the class with @Autowired.

• A
  2% (1)
• B
  88% (38)
• C
  2% (1)
• E
  7% (3)

Explanation

B is correct because annotating a class with @Component (or its specializations like @Service, @Repository, @Controller) enables implicit bean creation - Spring's component scan automatically detects and registers these classes as beans without any manual wiring code. D is correct because @Bean annotated methods inside a @Configuration class represent explicit bean creation - you write a method that returns the object, and Spring registers the return value as a managed bean.

Why the distractors fail:

• A & E are wrong because @Autowired is strictly for injecting (consuming) existing beans, never for creating them. It wires dependencies, it doesn't define them.
• C is wrong because @Bean belongs on methods inside a @Configuration class, not on the class itself. Placing @Bean on a class is not valid usage.

Memory tip: Think of the split as "Component = Come find me" (implicit, Spring scans and discovers it) vs. "@Bean method = I'll build it myself" (explicit, you write factory code). @Autowired is always the consumer, never the creator - if an answer says @Autowired creates a bean, it's a trap.
