OrlandoJUG Reading List ::: from JavaSpecialists
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.Issue 276 - Serializing Records
Java 14 Records (JEP359) reduce the boiler plate for simple POJOs. In this newsletter we look at what special magic is used to serialize and deserialize these new records.Issue 275 - EnhancedStream with Dynamic Proxy
In our previous newsletter we enhanced Java 8 Streams by decorating them with an EnhancedStream class. The code had a lot of repetition, which often leads to bugs if written by hand. In this newsletter we use a dynamic proxy to create an EnhancedStream. The resulting code is shorter and more consistent.Comment Wall
