\section{Footnotes and references}

\subsection{Inserting footnotes}

Make the text \enquote{March 2023} of the file 
\file{exercises/footnotes/footnotes.tex} appear as a footnote instead of in 
parentheses. Additionally, insert a clickable URL to the Java Development Kit 
as footnote: \\ \texttt{https://www.oracle.com/java/technologies/javase-downloads.html}
