Call the main method as follows:

<?php
use PHPJava\Core\JavaClass;
use PHPJava\Core\Stream\Reader\FileReader;

(new JavaClass(new FileReader('/path/to/HelloWorld.class')))
    ->getInvoker()
    ->getStatic()
    ->getMethods()
    ->call(
        'main',
        ["Hello World!"]
    );

Get the result

$ php /path/to/HelloWorld.php
Hello World!
