Introducing static typing

As a Software Engineer consultant in Zuhlke, I have an opportunity to work on various projects in various stages of development. Recently I have joined another existing project and I have found out again that we use Map<String, Object> too much, instead of mapping the objects to classes and benefit from all the goods of static typing. I think I have never before appreciated how powerful static typing is, and how much the lack of it can hurt (maybe that’s why I prefer to use Java over JavaScript?). The main reason for us to use maps is jdbi – we execute the SQL, we get back List<Map<String, Object>>. But mapping it to objects is too much effort so instead we keep working with maps. But what if mapping could be trivial and painless?
