summary
Shows Java 23 code in IntelliJ and claims modern Java is concise and concurrent. Demonstrates records replacing 40+ lines of getters/equals/toString with one declaration and an expression evaluator shrinking from ~60 lines to 19. Shows sealed classes plus pattern matching making exhaustive case handling simple. Runs a server demo where platform threads fail creating 10,000 native threads but virtual threads handle 10,000 clients fine. Mentions string templates (preview), vector API and foreign memory APIs for native interop.
