jre、jdk版本的選擇

每個jdk的更新版本包括奇數版本和偶數版本，如Java 8 Update 73 (8u73)和Java 8 Update 74 (8u74)。應該怎選擇哪個版本？

生産環境選8u73；測試環境可選8u74；

Each release has an odd (CPU) and an even (PSU) number. So in this case, 73 is the CPU (critical fixes) and 74 is the PSU (critical plus non-critical fixes)

General recommendation from oracle in a production environment is to use the CPU releases and start testing the PSU release in your test environments to prepare for the next CPU which will contain the previous PSU plus any new critical updates.

jre、server jre、jdk三個版本如何選擇？

Which Java package do I need?

Software Developers: JDK (Java SE Development Kit). For Java Developers. Includes a complete JRE plus tools for developing, debugging, and monitoring Java applications.

End user running Java on a desktop: JRE: (Java Runtime Environment). Covers most end-users needs. Contains everything required to run Java applications on your system.
