### Question:
Chars { public static boolean isLetterOrDigitOrPunc(char ch) { int i = Character.getType(ch); return Character.isLowerCase(ch) || Character.isUpperCase(ch) || Character.isDigit(ch) || (i>=20&&i<=30); }  static boolean isChar(String str); static boolean containChar(String str); static boolean isChar(char c); static boolean isChineseChar(char c); static String ToDBC(String input); static StringType char2StringType(CharType c); static StringType getStringType(String str); static TreeSet<CharType> getTypeSet(String str); static boolean isLetterOrDigitOrPunc(char ch); static boolean isLetterOrDigitOrPunc(String str); static boolean isPunc(String str); static CharType[] getType(String str); static CharType getType(char c); static String getTypeString(String str); static String type2String(CharType[] tag); static boolean isWhiteSpace(String w);  }### Answer:
@Test public void testIsLetterOrDigitOrPuncString() { String input = "VV( [^ ]+){0,1} 。( [^ ]+){0,1} 。( [^ ]+){0,1} 。 "; boolean s = Chars.isLetterOrDigitOrPunc(input); System.out.println(s); }
@Test public void testIsLetterOrDigitOrPunc() { char input = '我'; boolean s = Chars.isLetterOrDigitOrPunc(input); System.out.println(s); input = '９'; s = Chars.isLetterOrDigitOrPunc(input); System.out.println(s); input = '：'; s = Chars.isLetterOrDigitOrPunc(input); System.out.println(s); input = ':'; s = Chars.isLetterOrDigitOrPunc(input); System.out.println(s); input = '五'; s = Chars.isLetterOrDigitOrPunc(input); System.out.println(s); }
