Languages

Java

Java SDKs are stored in ~/Library/Java/JavaVirtualMachines or /Library/Java/JavaVirtualMachines.

/usr/bin/java looks for JAVA_HOME. Otherwise it will look for the JDK with the highest version.

Note that not all Java installations are full-featured. Some installations offer only runtime environment. Other have the development features eg. keytool to update the trust store.

Download different JDKs:

• Manually
• via IntelliJ
• brew — eg. brew install openjdk@11

Utils

• /usr/libexec/java_home to get the list of java versions

Env manager

• Set JAVA_HOME environment variable
• jenv

Auto switch to env based on proj

• For fish, refer to https://github.com/jenv/jenv.
