### Question:
StringNormalizer { public static String removePunctuation(String s) { return s.replaceAll("\\p{P}+", ""); }  static String reduceWS(String s); static String composed(String s); static String compatible(String s); static String removeDiacritics(String s); static String removePunctuation(String s); static String trim(String s); static String canonical(String s,
            boolean ignoreCase,
            boolean ignoreDiacritics,
            boolean ignorePunctuation); static String strip(String s); static String encode(String s);  }### Answer:
@Test public void testRemovePunctuation() { System.out.println("removePunctuation"); String s = "!\"#}-"; String expResult = ""; String result = StringNormalizer.removePunctuation(s); assertEquals(expResult, result); }
