# Chidamber and Kemerer Java Metrics

[![DOI](https://zenodo.org/badge/3928910.svg)](https://zenodo.org/badge/latestdoi/3928910)

The program _ckjm_ calculates Chidamber and Kemerer object-oriented metrics by processing the bytecode of compiled Java files. The program calculates for each class the following six metrics proposed by Chidamber and Kemerer.

* WMC: Weighted methods per class

* DIT: Depth of Inheritance Tree

* NOC: Number of Children

* CBO: Coupling between object classes

* RFC: Response for a Class

* LCOM: Lack of cohesion in methods

In addition it also calculates for each class

* Ca: Afferent couplings

* NPM: Number of public methods
