Chidamber and Kemerer Java Metrics

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
