I have added a list of the most important Java 11 features to my Java tutorial introduction.
The Java Iterator tutorial has been updated with information about the ConcurrentModificationException and remove() method.
The Java Try With Resources tutorial has been improved a lot. It explains how to have resources automatically closed after use, when used inside a Java try-with-resources construct.
I have compiled a list of data streaming products, and shortly explained what categories of products they belong to.
