The Java try with resources construct, AKA Java try-with-resources, is an exception handling mechanism that makes it possible to automatically close resources like an InputStream or a JDBC Connection when you are done with them. To do so, you must open and use the resource within a Java try-with-resources block. When the execution leaves the try-with-resources block, any resource opened within the try-with-resources block is automatically closed, regardless of whether any exceptions are thrown either from inside the try-with-resources block, or when attempting to close the resources.

http://tutorials.jenkov.com/svg/svg-coordinate-system.html The SVG coordinate system is different from a normal, cartesian coordinate sysem which you know from your math classes. The SVG coordinate system (like most computer graphics coordinate systems) has it Y-axis reversed, so that when Y-coordinates increases, points move down on the screen instead of up as in a cartesian coordinate system. ... https://www.youtube.com/watch?v=50Q4x3u1H2A

A Java enum is a mechanism for creating a collection of constants in Java. A Java enum is short for an "enumeration of constants". Typically you will create an enum containing related constants, e.g. HIGH, MEDIUM and LOW. This video explains how Java enums works. If you prefer a textual Java enum tutorial, I have one here: http://tutorials.jenkov.com/java/enums.html ... https://www.youtube.com/watch?v=1612Ngij7_c

The Java Queue interface represents a data structure where you add elements to the end of the queue, and remove them from the beginning of a queue. This is similar to how a queue in a supermarket works. Customers enqueue themselves at the end of the queue, and are served one by one from the beginning of the queue.
