How PHP runs on the JVM
<?php
echo 'hello' ;
System. out .println( &quot;hello&quot; );

11.
Some Code !
<?php
java_import( &quot;java.util.HashMap&quot; );
$map = new HashMap;
$map ->put( &quot;stuff&quot; , array ( 1 , 2 , 3 , 4 , 5 ));
var_dump( $map ->get( &quot;stuff&quot; ));
// prints: array(5) { ...

12.
Some more Code !
<?php
java_import( &quot;java.io.File&quot; );
class SubFile extends File {
function isThisCool() {
return TRUE ; // Way cool
}
}
$file = new SubFile( &quot;/&quot; );
var_dump( $file ->isDirectory());
var_dump( $file ->isThisCool());

13.
Some more Code !
<?php
java_import( &quot;java.util.ArrayList&quot; );
$list = new ArrayList();
$list ->add( &quot;Hello World!&quot; );
$list ->add( FALSE );
$list ->add( 1234567890 );
foreach ( $list as $key => $value ) {
echo &quot; $key $value &quot; ;
}

19.
One more bit of Code !
class Dynamic {
def storage = [:]
def invokeMethod(String name, args) {
println &quot;Hello!&quot;
}
def getProperty(String name) {
storage[name]
}
def setProperty(String name, value) {
storage[name] = value
}
}
<?php
groovy_import( &quot;dynamic.groovy&quot; );
$foo = new Dynamic();
$foo ->bar();
$foo ->guff = &quot;Hello World!&quot; ;
echo $foo ->guff;
