Thank you for this. I have been struggling with ObjectMapper for a few days now for a class assignment and your explanation perfectly explained the process and allowed me to see where I was making the mistakes.

Thanks a lot for this detailed explaination. Really helpful.
Just a request is it possible to show an example in which we are reading json directly from a third party API and converting it to object.
