I just noticed in Javadoc , WindowsPreferences class is missing.
I checked online versions of Java Docs for Java5,6,7 and Java 8.
But, this class is exists in JDK 7 (jdk1.7.0_79).
I can see this class as shown. Some other class such as java.util.pref.XmlSupport also missing in JavaDoc.
I was believing that JavaDoc documents every available class in Java, Is this belief wrong/not the reality?
Quoting the documentation around Javadoc generation -
The Javadoc tool parses the declarations and documentation comments in a set of Java source files and produces a corresponding set of HTML pages describing (by default) the public and protected classes, nested classes (but not anonymous inner classes), interfaces, constructors, methods, and fields.
