I've attended to this year's JavaDayTokyo.
My personal themes was learning about these.
- Java11, the LTS version being released half years after
- Other upcoming functions
- Especially about Project Valhalla. Recently, "How to treat huge size collection" is one of my important topic in my work.
These 8 JPEs will be added.
From them, the only update to "how to write code" looks this.
JEP 323: Local-Variable Syntax for Lambda Parameters
The "Next" LTS version is 17
The next LTS version after 11 is 17, it will be released on September, 2021. It is 3 years after than 11's release.
(I had thought LTS is released per 1.5 years, but not)
