Converting my comment to answer so that solution is easy to find for future visitors.

You may use regex replacement in Java:

str = str.replaceAll("(?m)^\\s+|\\s+$", "");

RegEx Details:

  • (?m): Enable MULTILINE mode so that ^ and $ are matched in every line.
  • ^\\s+: Match 1+ whitespaces at line start
  • |: OR
  • \\s+$: Match 1+ whitespaces before line end
