Chidamber and Kemerer Java Metrics

DOI

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
