\section{Java}
\subsection{Introduction}
\begin{itemize}
\item Compilen: \lstinline{javac main.java}
\item Ausführen: \lstinline{java main < sample.in}
\item Einlesen:
\lstset{language=Java}
\begin{lstlisting}
Scanner in = new Scanner(System.in); //java.util.Scanner
String line = in.nextLine(); //reads the next line of the input
int num = in.nextInt(); //reads the next token of the input as an int
double num2 = in.nextDouble(); //reads the next token of the input as a double
\end{lstlisting}
\end{itemize}
\subsection{BigInteger}
Hier ein kleiner überblick über die Methoden der Klasse BigInteger:
\begin{lstlisting}
//Returns this +,*,/,- val
BigInteger add(BigInteger val), multiply(BigInteger val), divide(BigInteger val), substract(BigInteger val)
//Returns this\(^e\)
BigInteger pow(BigInteger e)
//Bit-Operations
BigInteger and(BigInteger val), or(BigInteger val), xor(BigInteger val), not(), shiftLeft(int n), shiftRight(int n)
//Returns the greatest common divisor of abs(this) and abs(val)
BigInteger gcd(BigInteger val)
//Returns this mod m, this\(^{-1}\) mod m, this\(^e\) mod m
BigInteger mod(BigInteger m), modInverse(BigInteger m), modPow(BigInteger e, BigInteger m)
//Returns the next number that is greater than this and that is probably a prime.
BigInteger nextProbablePrime()
//Converting BigInteger. Attention: If the BigInteger is to big the lowest bits were choosen which fits into the converted data-type.
int intValue(), long longValue(), float floatValue(), double doubleValue()
\end{lstlisting}
