Java

Enterprise object-oriented Programming Language.

On my system, mostly managing with SDKMAN.

JDK Distributions

• JDK Distributions - SDKMAN! the Software Development Kit Manager
• Which Version of JDK Should I Use? | whichjdk.com

Some focus on distinct capabilities such as better performance on desktop. Some are just “this is the JDK you get on our platform.” No, I can’t really tell the difference. Minecraft behaves a little better for me under Temurin on Linux. That’s about all I know so far.

• Corretto - Amazon
• Dragonwell - Alibaba
• GraalVM
  • GraalVM Oracle
  • GrallVM Community
• Java SE Development Kit - Oracle
• Kona - Tencent
• Liberica - Bellsoft
• Liberica NIK - Bellsoft
  • Native Image Kit
• Mandrel - Red Hat
• OpenJDK - jdk.java.net
• OpenJDK - Microsoft
• SapMachine - SAP
• Semeru - IBM
• Temurin - Eclipse
• Trava - Trava
• Zulu - Azul Systems

LTS Releases

• Java version history - Wikipedia

I was going to add an EOL column but every JDK distribution has its own support calendar. For example, Oracle stopped commercial support for JDK 8 in 2022, while Azul will support it until the end of 2030.

Managing Projects

Gradle or Maven

Maven

sdk install maven

Maven – Introduction

• reduce details needed for build process
• provide a uniform build system
• Standardize project definitions
• encourage better development practices

pom.xml → Project Object Model

Gradle

sdk install gradle

mkdir project
cd project
gradle init

Gradle | Gradle vs Maven Comparison

• flexible
• reduce build time
• improve user experience
• support more complex dependency rules for composite builds

Build time savings is through incremental builds, so maybe worse numbers in CI context? #question
