Ascii { public static boolean isLowerCase(char c) { return (c >= 'a') && (c <= 'z'); } private  Ascii(); static String toLowerCase(String string); static String toLowerCase(CharSequence chars); static char toLowerCase(char c); static boolean isLowerCase(char c); static boolean isUpperCase(char c);  }### Answer:
@Test public void testIsLowerCaseOne() { assertFalse(Ascii.isLowerCase('{')); }
@Test public void testIsLowerCaseReturningTrue() { assertTrue(Ascii.isLowerCase('o')); }
@Test public void testIsLowerCaseTwo() { assertFalse(Ascii.isLowerCase('\"')); }
