Injecting One Class into Another

- If you have two classes, how would you inject one class into another using Spring Boot features?

To inject one class into another in Spring Boot, follow these simple steps:

1: Add @Component or @Service to the class you want to inject

@Component
public class ClassA {
    // your code here
}

2: Use @Autowired in the class where you want to inject it

@Component
public class ClassB {
    @Autowired
    private ClassA classA; // ClassA is injected here
}

Summary:

1: Mark the class to be injected with @Component or @Service.

2: Use @Autowired in the other class to inject it automatically.
