Java Checkstyle Rule To Restrict Method Empty Lines

Question

Is there a way to setup checkstyle to prevent leading, multiple or trailing empty lines in method bodies:

e.g.

private void a() {
-
int a = 1;
doStu         


        

Answer 1

To enforce no blank lines at the beginning and end of any block, you can use multi-line regular expression checks:

"^$" signifies the blank line.
