Do this recursively   public String replaceSpace String s       if  s length    lt  2            if s equals                   return              else             return s            if  s charAt 0                  return       replaceSpace s substring 1        else         return s substring 0  1    replaceSpace s substring 1

You need the  g  global  option  like this   var replaced   str replace    g          You can give it a try here   Unlike most other languages  JavaScript  by default  only replaces the first occurrence
