SERIALVER(1)

💅 serialver(1) — JDK Commands bestie 💅

okay so welcome to the serialver(1) page from the JDK Commands lineup, bestie. this is the tool that gives you the serialVersionUID for one or more classes in a form you can copy straight into an evolving class. iconic behavior, honestly.

✨ NAME ✨

serialver — return the serialVersionUID for one or more classes in a form suitable for copying into an evolving class.

🦋 SYNOPSIS 🦋

serialver [options] [classnames]

• options — this represents the command-line options for the serialver command. See Options for serialver.
• classnames — the classes for which serialVersionUID is to be returned.

🌸 DESCRIPTION 🌸

The serialver command returns the serialVersionUID for one or more classes in a form suitable for copying into an evolving class. When it’s called with no arguments, the serialver command prints a usage line. periodt.

👑 OPTIONS FOR SERIALVER 👑

• -classpath path-files — sets the search path for application classes and resources. Separate classes and resources with a colon (:).
• -Joption — passes the specified option to the Java Virtual Machine, where option is one of the options described on the reference page for the Java application launcher. For example, -J-Xms48m sets the startup memory to 48 MB.

🎀 NOTES 🎀

The serialver command loads and initializes the specified classes in its virtual machine, and by default, it doesn’t set a security manager. If the serialver command is to be run with untrusted classes, then a security manager can be set with the following option:

-J-Djava.security.manager

When necessary, a security policy can be specified with the following option:

-J-Djava.security.policy=policy_file

bestie, this is the “untrusted classes” part, so don’t skip the security-manager convo. it’s giving responsible main character energy 🫶

mwah 💋 that was serialver(1) from JDK 21, dated 2023 — version-era slay, no cap. 🌈✨
