OrlandoJUG Reading List ::: from JavaSpecialists
Issue 285 - I/O Stream Memory Overhead
Each PrintStream uses about 25kb of memory. This might seem reasonable if we only have System.out and System.err. But what happens if we try create millions? And why do they use so much memory?Issue 284 - java.util.PrimitiveIterator.OfInt
Java 8 Streams were the first time that Java deliberately split utility classes into multiple versions to be used for Object, int, long and double. This design was also applied to Iterator, which now has specialized types for these primites in the form of the PrimitiveIterator. In this newsletter we have a look at how we can use that in our own primitive collections.Issue 283 - Four Billion Changes
A nice puzzle to brighten your day - how can we make the Iterator think that the List has not been changed?Issue 282 - Biased locking a goner, but better things Loom ahead
Biased locking has made unnecessary mutexes cheap for over a decade. However, it is disabled by default in Java 15, slated for removal. From Java 15 onwards we should be more diligent to avoid synchronized in places where we do not need it.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?Comment Wall
