Pattern pattern = Pattern. compile (regex );
Matcher matcher = pattern. matcher (str );
StringBuffer result = new StringBuffer ();
While (matcher. find ()){
StringBuffer replace = new StringBuffer ();
Replace. append ("<a href = \" "). append (matcher. group ());
Replace. append ("\" target = \ "_ blank \"> click to open the link </a> ");
Matcher. appendReplacement (result, replace. toString ());
