### Question:
XmlUtils { public static boolean isNcNameStartCharacter(char ch) { byte b = CHARS[ch]; return (64 < b && b < 127) || (-64 < b && b < 0); } private  XmlUtils(); static boolean isNcNameStartCharacter(char ch); static boolean isNcNameCharacter(char ch); static String createValidId(String value);  }### Answer:
@Test public void testIncorrectNcNameStartCharacters() { assertFalse(XmlUtils.isNcNameStartCharacter('1')); assertFalse(XmlUtils.isNcNameStartCharacter('<')); assertFalse(XmlUtils.isNcNameStartCharacter('-')); assertFalse(XmlUtils.isNcNameStartCharacter('#')); }
@Test public void testCorrectNcNameStartCharacters() { assertTrue(XmlUtils.isNcNameStartCharacter('a')); assertTrue(XmlUtils.isNcNameStartCharacter('A')); assertTrue(XmlUtils.isNcNameStartCharacter('_')); }
