print information about Java source file

## NAME

jv-scan - print information about Java source file

## SYNOPSIS

jv-scan \[**--no-assert**\] \[**--complexity**\] \
     \[**--encoding**=*name*\] \[**--print-main**\] \
     \[**--list-class**\] \[**--list-filename**\]\
     \[**--version**\] \[**--help**\]\
     \[**-o** *file*\] *inputfile*...

## DESCRIPTION

The `"jv-scan"` program can be used to print information about a Java source file (*.java* file).

## OPTIONS

- **--no-assert**

  Don't recognize the `"assert"` keyword, for backwards compatibility with older versions of the language specification.

- **--complexity**

  This prints a complexity measure, related to cyclomatic complexity, for each input file.

- **--encoding=***name*

  This works like the corresponding **gcj** option.

- **--print-main**

  This prints the name of the class in this file containing a `"main"` method.

- **--list-class**

  This lists the names of all classes defined in the input files.

- **--list-filename**

  If `"--list-class"` is given, this option causes `"jv-scan"` to also print the name of the file in which each class was found.

- **-o** *file*

  Print output to the named file.

- **--help**

  Print help, then exit.

- **--version**

  Print version number, then exit.
