\arara\ can be extended at runtime with code from JVM languages, such as Groovy, Scala, Clojure and Kotlin. The tool can load classes from \rbox{class} and \rbox{jar} files and even instantiate them. This section introduces methods related to class loading and object instantiation.

-According to the \href{https://en.wikipedia.org/wiki/Ordered_pair}{Wikipedia entry}, in mathematics, an \emph{ordered pair} $(a, b)$ is a pair of objects. The order in which the objects appear in the pair is significant: the ordered pair $(a, b)$ is different from the ordered pair $(b, a)$ unless $a = b$. In the ordered pair $(a, b)$, the object $a$ is called the \emph{first} entry, and the object $b$ the \emph{second} entry of the pair. \arara\ relies on this concept with the helper \rbox{Pair<A, B>} class, in which \rbox{A} and \rbox{B} denote the component classes, i.e, the types associated to the pair elements. In order to access the pair entries, the class provides two methods:

In order to access the pair entries, the class provides two property accessors:
\begin{description}
-\item[\mtbox{first()}\hfill\rrbox{A}] This method, as the name implies, returns the first entry of the ordered pair, as an \rbox{A} object. It is important to observe that, from the MVEL context, as the method constitutes a property accessor (namely, a getter), the parentheses can be safely omitted.
+\item[\mtbox{first}\hfill\rrbox{A}] This property accessor, as the name implies, returns the first entry of the ordered pair, as an \rbox{A} object.
-\item[\mtbox{second()}\hfill\rrbox{B}] This method, as the name implies, returns the second entry of the ordered pair, as a \rbox{B} object. It is important to observe that, from the MVEL context, as the method constitutes a property accessor (namely, a getter), the parentheses can be safely omitted.
+\item[\mtbox{second}\hfill\rrbox{B}] This property accessor, as the name implies, returns the second entry of the ordered pair, as a \rbox{B} object.
\end{description}
Keep in mind that the entries in the \rbox{Pair} class, once defined, cannot be modified to other values. The initial values are set during instantiation and, therefore, only entry getters are available to the user during the object life cycle.
