Java 9 defines a minimal logging API which platform classes can use to log messages, together with a service interface for consumers of those messages. In this tutorial, we’re gonna take a look at new Java 9 Platform Logging API and an example that implements LoggerFinder service which can route platform log messages to the logging framework for application logger instead of system logger.

Java 9 provides a common logging system for JVM components with extremely detailed level, an infrastructure to do the logging. With new command-line option -Xlog for all logging followed settings, Unified JVM Logging gives us a precise, easy-to-configure tool to do a root cause analysis of complex system-level JVM components.
Javadoc is the tool that can generate documentation for API in HTML format. In previous version of JDK, it’s HTML 4.01 – an old standard. JDK 9 Javadoc now supports to generate HTML5 markup, improves search capability and Doclint.
Internationalization Enhancements for JDK 9 include: Unicode 8.0, UTF-8 Properties Files and enabling CLDR Locale Data by Default.

In earlier version of Java, Image I/O Framework javax.imageio provides a standard way to plug-in image codecs for some formats such as PNG and JPEG. But TIFF is still missing from this set. It was packaged in com.sun.media.imageio.plugins.tiff before. Java 9 TIFF Image I/O plugins has a new package called javax.imageio.plugins.tiff which is renamed from com.sun.media.imageio.plugins.tiff.
In this article, we’re gonna take a look at that package and test a simple example.
To improve Java Future, Java 8 provides CompletableFuture which can execute some code whenever its ready. In this article, we’re gonna take a look at new Java 9 CompletableFuture API that supports delay and timeout.
