Indentation help

[suzannepelz]

I need to add a line to my .emacs file for java code so that I can
indent concatenated long Strings as follows:

FROM THIS:
String description = "this is a really long description " +
"that I need to put on two lines.";


TO THIS (with next line indented two spaces):
String description = "this is a really long description " +
  "that I need to put on two lines.";


Thank you!
