What is ckjm tool?

Introduction. 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, and displays them on its standard output, following the class’s name: WMC: Weighted methods per class.

What are the metrics for the connection file using CKJM?

ckjm — Chidamber and Kemerer Java Metrics

• 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.

What is chidamber and kemerer metrics?

Chidamber and Kemerer’s metrics suite: a measurement theory perspective. Abstract: The metrics suite for object-oriented design put forward by Chidamber and Kemerer (1994) is partly evaluated by applying principles of measurement theory.

How do I run CKJM?

To run ckjm you must run java with the -jar flag, providing as its argument the location of the file ckjm. jar . Next, you can specify as arguments the Java class files you want to analyze. (Replace the sequence /usr/local/lib/ckjm-1.5.

What are CK metrics?

], now referred to as the CK metrics, have become well known and widely accepted by the software engineering community. The CK metrics can be used to measure some characteristics of OO systems such as classes, message passing, inheritance, and encapsulation.

What are the six CK metrics for OO design?

The suite comprises six metrics: Weighted Methods per Class (WMC), Coupling Between Objects (CBO), Depth of Inheritance Tree (DIT), Number of Children (NOC), Response For a Class (RFC), and Lack of Cohesion in Methods (LCOM).

What is mood metrics in software engineering?

Abstract: MOOD metrics are well known metrics used to measure some characteristics of the Object-Oriented programs. In this research, a system, based on the MOOD, has been developed to evaluate and grade Java programs.
