Java – can anyone provide a good explanation for dagger 2?

It's really hard for me to understand dagger 2 dependency injection system

I understand that using the @ inject annotation tells the dagger that we need to provide some types of instances here

However, I don't understand the various roles of other components, such as @ module, @ component, @ provides, and how they work together to provide appropriate instances for appropriate dependencies

Can anyone explain it briefly?

Solution

I suggest you read:

I think it will help to understand
