It can scan the code to directly connect to DSH, and if you want to use it on the public network, it also supports using internal network penetration
You can chat with DSH, answer DSH questions, approve permissions, create new chats, etc.
I hope everyone can provide more opinions

jir helps you manage Java versions without fighting JAVA_HOME.
Install a JDK, switch to it, and keep your active Java runtime behind one stable path: home/occupy.
If you often switch between Java 8, 17, 21, or different vendors like Temurin, Corretto, Zulu, Oracle, and Microsoft OpenJDK, jir keeps that workflow simple.
You can set JAVA_HOME to home/occupy once. After that, jir use 21:temurin switches Java without editing environment variables again.
On Windows, switching uses a directory junction, so it is fast and does not copy the whole JDK.
Download or build the Windows GUI installer:
dist/jir-0.1.0-windows-x64-gui-setup.exe
The installer lets you choose where jir lives. It can also add jir to PATH and set JAVA_HOME for you.
After installing, open a new terminal and check:
jir -h
See what you can install:
jir ls -i
Install Java 21. If there are multiple vendors, jir will let you choose one:
jir i 21
Already know what you want?
jir i 21:temurin
Switch to it:
jir use 21:temurin
Check what is active:
jir current
Remove something you no longer need:
jir uni 21:temurin
jir, jir -h, jir -help, jir --help: show help.jir ls: show installed JDKs.jir ls -i: show installable JDKs.jir i 21: install Java 21 and choose a vendor.jir i 21:temurin: install a specific distro.jir use 21: choose an installed Java 21 distro and activate it.jir use 21:temurin: activate a specific installed distro.jir current: show the active Java runtime.jir uni 21:temurin: uninstall a JDK after confirmation.
