## God Classes
The first part of the project requires to label some classes of the _Xerces_
project as "God classes" based on the number of methods each class has.
Specifically, I label "God classes" the classes that have a number of methods
six times the standard deviation above the the mean number of methods, i.e. where
the condition
$$|M(C)| > \mu(M) + 6\sigma(M)$$
holds.
To scan and compute the number of methods of each class I use the Python library `javalang`, which implements the Java AST and parser. The Python script
`./find_god_classes.py` uses this library to parse each file in the project and
compute the number of methods of each class. Note that only non-constructor methods are counted (specifically the code counts the number of `method` nodes in each `ClassDeclaration` node).
Then, the script computes mean and standard
deviation of the number of methods and filters the list of classes according to the
condition described above. The file `god_classes/god_classes.csv` then is outputted
listing all the god classes found.
The god classes I identified, and their corresponding number of methods
can be found in Table [1](#tab:god_classes){reference-type="ref"
reference="tab:god_classes"}.

: Identified God Classes
:::
The god classes I identified, and their corresponding number of methods
can be found in Table [1](#tab:god_classes){reference-type="ref"
reference="tab:god_classes"}.
Note: the number of methods was computed by considering only methods and not constructors.
