if(myVariable == FIRST...

Based on this question it appears that the default template for CheckStyle will allow if else ladders to separate the if and else with a line break.
Meaning I would like this code to be flagged as a violation:

So the generic regexp else[ \t]*[\r\n]+[ \t]*if is indeed a quick way.
Of the Checkstyle SDK Gui does not make any difference between:

Also, try a mapping instead of the if/else.
If you want it to always run, remove the conditional in parentheses .

If Else is clear and easy to read.
Otherwise a table-based approach looks, which can be faster, none .

Sometimes, I feel like it is easier to check if all of the conditions are true, but then only handle the "other" situation.
I guess I sometimes feel that it is easier to know that something is valid, and assume all other cases are not valid.
For example...
