## NAME

- *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.

## 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*
