public final class EmptyLinesCheck extends com.puppycrawl.tools.checkstyle.api.AbstractCheck
Check for empty lines inside methods and constructors.

We believe that comments and empty lines are evil. If you need to use an empty line in order to add a vertical separator of concepts - refactor your code and make it more cohesive and readable. The bottom line is that every method should look solid and do just one thing. This class is thread safe. It relies on building a list of line ranges by visiting each method definition and each anonymous inner type. It stores these references in a non-static thread local.
