All of them are better then never wrapping the line at all.

Agreed

I'd love to hear about your favorites sometime because I don't really have a favorite.

So, here's my personal list:

• Don't end lines with (

Instead of

Thing ReaaaaaaaalllllllllllyLongFoo = SomeLongThing.someMethod(
    arg1, arg2, arg3);

Thing ReaaaaaaaalllllllllllyLongFoo =
    SomeLongThing.someMethod(arg1, arg2, arg3);

• Don't let args be lonely by themselves if possible

Exception e = ElasticsearchException("this is a really long message and other things",
        "another string", err); // <-- 'err' has a friend

Exception e = ElasticsearchException("this is a really long message and other things",
        err); // <-- it's so lonely!

This actually comes from prose, where justification and indenting usually should never put a single word on a line by itself (it should pull a word from the previous line down so it's not lonely). Tools like par do this too if I recall correctly (I could be wrong, I can consult my style manuals).

• If splitting a really long string, put the + at the end instead of the beginning of the next line

So instead of:

String foo = "this is a "
        + "really long string";

String foo = "this is a " +
        "really long string";

Because it makes it more apparent that the string is continuing below when you read the first line.

• Don't put ); on its own line

It's totally okay to have }); on its own line for things like classes and Runnables and such, but not things like:

Object foo = MyAwesomeObject("foo", 12.03, 4,
        "more arguments"
        );
