Objects & objects vs primitives

Great that you are still with us! After getting acquainted with the ultimate basics of Java, it’s now time to look a bit more in-depth to zoom in on fields, primitives, operations and casting. This week is going to be substantially more work than last, but the good news is that you will learn a lot!
