# serialver

Returns the serial version UID for specified classes.

## Synopsis

serialver [ options ] [ classnames ]

options

  The command-line options. See Options.

classnames

  The classes for which the `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 called with no arguments, the `serialver` command prints a usage line.

## Options

-classpath path-files

  Sets the search path for application classes and resources. Separate classes and resources with a colon (:).

-show

  Displays a simple user interface. Enter the full class name and press either the Enter key or the Show button to display the `serialVersionUID`.

-Joption

  Passes `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. See `java`(1).

## Notes

The `serialver` command loads and initializes the specified classes in its virtual machine, and by default, it does not 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>
