OrlandoJUG Reading List ::: from JavaSpecialists

Issue 309 - TreeSet with Custom Comparator

We can construct our TreeSet with our own Comparator, however, we need to be careful that it conforms to the specification. The Comparator needs to be consistent with equals() and hashCode() of the elements, otherwise we might end up with a TreeSet with non-symmetric equals() behaviour.

Issue 308 - Formatting Inlined @value in Javadocs

Javadoc specifies the details of our methods using special tags such as @param and @return. After Java 5, we did not see new standard Javadoc tags for 13 years. The hope was that annotations would replace the chaos of doclets. But tags have not disappeared. In this newsletter, we examine several new tags to improve our Javadoc experience.

Issue 307 - AccessFlag Set for Modifiers

Reflection returns the modifiers of class elements as an unqualified int bitset. Unfortunately some of the bits have a different meaning depending on their context. For example, a method can have their transient bit set, even though that does not make sense for a method. In Java 20, we now have a more accurate and robust enum based representation for modifiers.

Issue 306 - Measuring compact strings memory savings

JEP 254 replaced the char[] in our Strings with byte[]. How much memory does this save in our Strings? In this newsletter we show how we can determine this from a heap dump file.

Issue 305 - Contributing BigInteger.parallelMultiply() to OpenJDK

BigInteger has clever algorithms for multiplying large numbers. Unfortunately multiply() is single-threaded. Until now. In this newsletter I describe how the new parallelMultiply() method works and also how we can all contribute to the OpenJDK.
