What should be the range of cyclomatic complexity for JAVA

Question

I want to know that what should be the standard range of cyclomatic complexity?

And does it depends on language or platform or it is common for all?

I am using State of Flow - EclipseMetrics which is a Eclipse plugin calculates various metrics for your code during build cycles and warns you, via the Problems view, of ‘range violations’ for each metric.

Answer 1

As low as possible, just like any other code. Generally it's recommended to keep the cyclomatic complexity below 5.

In reality, that's easier said than done though. Good luck!

Answer 2

I have refered this link - http://www.javaworld.com/community/node/1005

Cyclocmatic complexity = Number of decision points + 1

The decision points may be your conditional statements like if, if … else, switch , for loop, while loop etc.

The following chart describes the type of the application.

Cyclomatic Complexity lies 1 – 10  To be considered Normal applicatinon

Cyclomatic Complexity lies 11 – 20  Moderate application

Cyclomatic Complexity lies 21 – 50  Risky application

Cyclomatic Complexity lies more than 50  Unstable application
