Stack Overflow was launched over 11 years ago. Since then more than 19 million questions were asked and only Jon Skeet read them all. Below you can find a handful of my favourite questions. Each of them is answered in depth, providing a chance to learn something interesting.
Why does array[idx++]+=“a” increase idx once in Java 8 but twice in Java 9 and 10?
Why filter() after flatMap() is “not completely” lazy in Java streams?
