This document outlines a talk about Java given by Davis Chen. The agenda includes discussing why not Java, Lombok, Spring Data JPA, Spring Boot, and conclusions. Lombok is introduced as a way to eliminate boilerplate code like getters and setters. Spring Data JPA allows defining data access in a generic way through interfaces and consistent naming conventions. Spring Boot aims to create standalone applications quickly without XML configuration and includes embedded web servers. The talk concludes that Java remains a good choice for platforms and backends in most cases.
