The 's' replaces one space match at any given time however the 's+' replaces The entire Area sequence at the same time with the second parameter.

Having said that x.replaceAll("s+", ""); will probably be a lot more productive means of trimming spaces (if string may have a number of contiguous spaces) due to the fact of doubtless significantly less no of replacements because of the to incontrovertible fact that regex s+ matches one or maybe more spaces at once and replaces them with vacant string.
