 \section{Syntax}
 In Scala gibt es sog. \textit{values}, die durch das Schlüsselwort \texttt{val}\xindex{val}
 angezeigt werden. Diese sind Konstanten. Die Syntax ist der UML-Syntax ähnlich.
 
-\begin{verbatim}
-val name: type = value
-\end{verbatim}
+\inputminted[numbersep=5pt, tabsize=4]{scala}{scripts/scala/val-syntax.scala}
 
 Variablen werden durch das Schlüsselwort \texttt{var}\xindex{var} angezeigt:
 
-\begin{verbatim}
-var name: type = value
-\end{verbatim}
+\inputminted[numbersep=5pt, tabsize=4]{scala}{scripts/scala/var-syntax.scala}
 
 Methoden werden mit dem Schlüsselwort \texttt{def}\xindex{def} erzeugt:
 
-\begin{verbatim}
-def name(parameter: String): Unit = { code body... }
-\end{verbatim}
+\inputminted[numbersep=5pt, tabsize=4]{scala}{scripts/scala/method-syntax.scala}

+Klassen werden wie folgt erstellt:
