ckjm calculates Chidamber and Kemerer object-oriented metrics by processing the bytecode of compiled Java files. For each class given, the program calculates 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; and LCOM, lack of cohesion in methods. In addition, ckjm also calculates each class's afferent couplings (Ca) and its number of public methods (NPM).
