Cognitive Complexity
Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.
A method's cognitive complexity is based on a few simple rules:
- Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
- Code is considered more complex for each "break in the linear flow of the code"
- Code is considered more complex when "flow breaking structures are nested"

Checks for long lines.
Rationale: Long lines are hard to read in printouts or if developershave limited screen space for the source code, e.g. if the IDEdisplays additional information like project tree, class hierarchy,etc.

'import' should be separated from previous line. Open
import android.content.res.Resources;- Read upRead up
- Exclude checks
Checks for empty line separators before package, all import declarations,fields, constructors, methods, nested classes,static initializers and instance initializers.
Checks for empty line separators before not only statements butimplementation and documentation comments and blocks as well.
ATTENTION: empty line separator is required between token siblings,not after line where token is found.If token does not have same type sibling then empty lineis required at its end (for example for CLASS_DEF it is after '}').Also, trailing comments are skipped.
ATTENTION: violations from multiple empty lines cannot be suppressed via XPath:#8179.

Extra separation in import group before 'org.hamcrest.Description' Open
import org.hamcrest.Description;- Read upRead up
- Exclude checks
Checks that the groups of import declarations appear in the order specifiedby the user. If there is an import but its group is not specified in theconfiguration such an import should be placed at the end of the import list.
