# JavaTXCompiler Klasse
* Konstruktor hat einen weiteren Parameter
* contextPath
* Arrays aus URLs (file-urls)
* Parameter ist Optional
* wird er gesetzt, so werden Classfiles aus den übergebenen Pfaden geladen
* die übergebenen Pfade müssen dabei die Source-Roots sein
* Beispiel:
`import de.test.Klasse;`
* `Klasse.class` liegt in `output/de/test/Klasse.class`
* dann muss contextpath auf `output` gesetzt werden
* wird der Parameter nicht übergeben, so wird der Sourceroot auf das Verzeichnis gesetzt, in dem der Compiler ausgeführt wird
* dies ist das Verhalten vom javac Compiler
* generateBytecode - Methode hat neuen Parameter: path
* wird hier null übergeben, so wird die class-File in den gleichen Ordner wie die übergebene .jav File geschrieben
* wird hier ein Pfad übergeben, so gilt dieser als output root.
* Klassen werden in outputRoot/package/name/KlassenName.class geschrieben

\begin{document}
\section{Generics sind notwendig}
Generics können nicht ignoriert werden.
Folgender Fall ist Typisierbar:
\begin{program}
<T> T m1(T x){
return m2(x);
}
m2(x){
m1(1);
m2("Test");
return m1(x);
}
\end{program}
Beim weglassen des Generics T wäre es aber nicht mehr möglich.
Dann erhält jeder Constraint, welcher in Verbindung mit der Methode m1 steht
den selben TPH.
