Difference between @Bean and @Autowired

@Bean is used when you want to tell spring that this is the instance of this class. please give it me whenever I ask for istance of this class.

@Autowired is used to get the instance of the class which is annotated with the @Bean means you get the instance using the @Autowired.

you use @Bean for those classes object which you want to decide about how the object should be created for that respective class.

Example:
Class Bird({
    String name;
    @Bean
    public Bird(){
        name = "Sparrow";
    }
}

Class Zoo{
    @Autowired
    private Bird bird;
}

So, here in the @Autowired will get the object from the bird class using the constructore annotated with the @Bean class.
