# serialver - The Serial Version Command

> The serialver command returns the `serialVersionUID`.

## SYNOPSIS

>     serialver [ options ] [ classnames ]

> > `options`
> >   Command-line options, as specified in this document.
> > `classnames`
> >   One or more class names

## DESCRIPTION

> serialver returns the `serialVersionUID` for one or more classes in a form suitable for copying into an evolving class. When invoked with no arguments it prints a usage line.

## OPTIONS

> -classpath <directories and zip/jar files separated by :>
>   Set search path for application classes and resources.
> -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.
> -J option
>   Pass 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 megabytes.

## 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 serialver is to be run with untrusted classes, a security manager can be set with the following option:

> > `-J-Djava.security.manager`

> and, if necessary, a security policy can be specified with the following option:

> > `-J-Djava.security.policy=<policy file>`
