Java StAX Tips

StAX stands for Streaming API for XML APIs, meaning the XML reader and writer that are contained in package javax.xml.stream of the Java standard library. The first tip is to know this API exists and you should use it! The older APIs, Simple API for XML APIs (SAX parser) and Document Object Model APIs (W3C […]

Comment Converter from C# to Java

C# XML comments and Javadoc comments have a large overlap in semantic functionality but annoyingly use a very different syntax. C# XML comments are usually introduced by three slashes /// on each line and use XML elements for semantic information, whereas Javadoc employs standard comment blocks starting with /** (also optionally supported by C# but […]

Java Client VM Remeasured

After upgrading my computer system some months ago and finishing the port of Tektosyne for Java just recently, I decided it’s time to update the measurements on my comparison page for Oracle’s Java Client and Server VMs on Microsoft Windows. As a reminder, the core problem is that any modern Windows system should automatically run […]

Tektosyne Library for Java

Tektosyne 6.0 is now available for download, its first release in Java. You can download the code package itself, with complete source code and prebuilt JAR files, as well as an extensive PDF User’s Guide. This is a partial port of the previous version which was written in C# for the Windows .NET Framework. The […]

Class Diagrammer 2.1.0 Released

Wrapping up the Java port of my Tektosyne library (for computational geometry and graph algorithms), I recreated a number of UML diagrams for documentation, using my recently ported Class Diagrammer. That was its biggest project to date, and sure enough a large number of fixes and enhancements resulted. Class Diagrammer 2.1.0 is now available for […]

Java Method Reference Evaluation

Along with lambda expressions, Java SE 8 introduced method references as a shorthand notation. These are mostly used to reference static methods (e.g. Double::toString) or constructors (e.g. String[]::new), and these uses are straightforward. However, method references to instance methods can yield results that differ from lambda expressions in surprising ways. This is because the invocation […]

Diagrammer Fixes & Samples

I have been using my recently released Class Diagrammer for Java to document two more of my projects, and along the way inevitably found a number of bugs that needed fixing and features that needed adding. So here is Class Diagrammer 2.0.1 with the following fixes, enhancements, and new samples. 2016-06-05: Minor update to version […]

Class Diagrammer for Java

Class Diagrammer 2.0 is now available for download, written in Java & JavaFX and designed to reverse-engineer Java JAR files into UML class and package diagrams. This is mostly a direct rewrite of the previous version which was written in C# and operated on .NET Framework assemblies. The download page still offers the final .NET […]

JavaFX and JAVA_TOOL_OPTIONS

JavaFX provides some dedicated system properties to customize its behavior. Usually these are specified as command-line flags on the java/javaw invocation, using the syntax “java -Dname=value” followed by the JavaFX application path. I’ve previously noted two especially useful ones, as of Java SE 8u66-77: -Dprism.order=sw enables software rendering, even if JavaFX thinks hardware acceleration is […]
