## 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 called with no
arguments, the `serialver` command prints a usage line.

## Options for serialver

`-classpath` *path-files*
:   Sets the search path for application classes and resources. Separate
    classes and resources with a colon (:).

`-J`*option*
:   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.

## Warning

The `serialver` command loads and initializes the specified classes in
order to determine their `serialVersionUID` values. *DO NOT RUN* `serialver`
on untrusted classes.
