OrlandoJUG Reading List ::: from JavaSpecialists
Issue 281 - Puzzle 2: Is it garbage?
In our next puzzle, we up the ante a bit. We prevent GC during the test() method by storing a strong reference to all our Vectors. Cock and bull story, or are we struggling to identity our biases?Issue 280 - Puzzle: What's up with Vector?
For today's puzzle, we are getting elements from Vector, sequentially and in parallel. But why is the performance so much worse in Java 15-ea+28?Issue 279 - Upgrading ReadWriteLock
The Java ReentrantReadWriteLock can never ever upgrade a read lock to a write lock. Kotlin's extension function ReentrantReadWriteLock.write() cheats a bit by letting go of the read lock before upgrading, thus opening the door for race conditions. A better solution is StampedLock, which has a method to try to convert the lock to a write lock.Issue 278 - Free Memory
How much memory was wasted when an additional boolean field was added to java.lang.String in Java 13? None at all. This article explains why.Issue 277 - Strings with Zero HashCode
In Java 2, the computational time complexity of String#hashCode() became linear, as it used every character to calculate the hash. Java 3 cached the hash code, so that it would not need to be recalculated every time we called hashCode(), except in the case that the hash code was zero. Java 13 finally fixes that inefficiency with an additional boolean field.Comment Wall
