Reading List ::: from JavaSpecialists

Issue 291 - Snakes and Ladders

"Would you like to play with me?" - Summer holidays are a good time to relax and whip out a board game or two. In this newsletter we explore a children's favourite - snakes and ladders, with a simulation written in Java.

Issue 290 - CopyOnWriteArrayList and Collection.toArray()

When is it safe for a CopyOnWriteArrayList to accept the result from a toArray() method? In the past, the only thing that mattered was that the type was Object[]. But this was changed in 2020 to only accept the array if the source was a java.util.ArrayList.

Issue 289 - MergingSortedSpliterator

If we have a List>, each stream with sorted elements, how can we generate a sorted Stream, taking one at a time from each stream? In this newsletter we show how to do that with the Stream API and by writing our own MergingSortedSpliterator.

Issue 288 - Weakly Consistent Iteration

How consistent is weakly-consistent iteration? And which collections return weakly-consistent iterators? How do we know? Join us as we explore what weakly-consistent means with concrete examples.

Issue 287 - @PolymorphicSignature

MethodHandles annotate the invoke() methods with @PolymorphicSignature. In this newsletter we see how this can help to avoid unnecessary object creation.
