As I understand, using modules allows us to control some dependencies. I mean that we can allow one module to interact with another one but not vise versa. We also can make some reusable things and we can make deploying easier, if, for example, put all tests stuff into a separate module and won't deploy it to production. I haven't eve...
I am using Netbeans and am trying to find a way for the IDE to auto-generate the code for me. I remember binding a JLabel's text to a column in the selected row of the JTable before, but in that case, the JTable's values were from an entity manager, and it was very easy.
