Chapter 9. Analyzing Complexity and Design
In this chapter, we will discuss how Sonar reports on complexity and the measures it supports. Firstly, we will clarify how complexity in Java programs is calculated and then look into the concepts of coupling, cohesion, and dependencies.

In this chapter we will cover:
- Measuring software complexity
- Cohesion and coupling
- Sonar code complexity metrics
- The Response for Class metric
- Lack of cohesion and the LCOM4 metric
- Locating and eliminating dependencies
Measuring software complexity
Software and its complexity could be described as ...
