remove a trailing slash from a string in Java

gistfile1.java

s = s.replaceAll("/$", "");

// or

s = s.replaceAll("/\\z", "");

// slightly faster

if (s.endsWith("/")) {
  s = s.substring(0, s.length() - 1);
}

// slightly faster, but a bit ugly

s = s.substring(0, s.length() - (s.endsWith("/") ? 1 : 0));
