The other day I was trying to assign a container of, let’s say, numbers distributed across 20 groups, to a container with a smaller size that can only hold up to 6 groups. The bigger group has values from 0 to 19. It also means that group 0 will always have zero number value, 1…
The other day, I was working on a huge JSON object that had a number of collections in it. The entire object had to be saved into a relational database, which means I was mapping out the raw JSON data to its logical representation as database tables. Though the object wasn’t that complicated, it did…
Using Repository interfaces, one can develop applications with an underlying database rapidly in Spring Boot. The Spring Data JPA handles the abstraction of the persistence layer quite well. Many times you probably won’t need anything else beyond what it has to offer. A lot can already be done with the exposed methods for data access…
As a back-end developer, consuming JSON objects is pretty much very common. I think it is second only to publishing data in JSON format, the other end of what is usually a 2-way street.

Elementary, you might think, but I’ve been out of this kind of programming for a while. For this exercise, it’s about looking for the number closest to zero. Since the…
