Example 624. Force an exception and handle it

echo "<h2>Testing java.util.StringTokenizer</h2>"; 

$str = new Java("java.util.StringTokenizer", "This is a test string"); 
while ($str->hasMoreTokens()) { 
    echo "Got token from string: <b>" . $str->nextToken() . "</b><br>\n"; 
} 
 
echo "<h2>Testing Exceptions</h2>"; 
echo "This should print out 'No exception':<br>\n"; 
if ($ex = java_last_exception_get()) { 
    echo "Got exception: " . $ex->toString() . "<br>\n"; 
} else { 
    echo "No exception<br>\n"; 
} 
 
// Force an exception (using '@' to suppress the PHP-level warning): 
@$str->nextToken(); 
 
echo "This should print out some exception information:<br>\n"; 
if ($ex = java_last_exception_get()) { 
    echo "Got exception: " . $ex->toString() . "<br>\n"; 
} else { 
    echo "No exception<br>\n"; 
}

/* Without this line, successive reloads of the script could cause this last exception to
