### Question:
PropertyUtils { public static boolean isFalse(Map<String, Object> props, String key) { if (props == null || key == null) { return false; } return isFalse(props.get(key)); } private  PropertyUtils(); static boolean isTrue(Map<String, Object> props, String key); static boolean isFalse(Map<String, Object> props, String key); static boolean isTrue(Object property); static boolean isFalse(Object property); static Long getLong(Message message, String key); static Integer getInteger(Message message, String key);  }### Answer:
@Test public void testIsFalseWithMap() { Map<String, Object> props = new HashMap<>(); assertFalse(PropertyUtils.isFalse(props, TEST_KEY)); props.put(TEST_KEY, "true"); assertFalse(PropertyUtils.isFalse(props, TEST_KEY)); props.put(TEST_KEY, Boolean.TRUE); assertFalse(PropertyUtils.isFalse(props, TEST_KEY)); props.put(TEST_KEY, "false"); assertTrue(PropertyUtils.isFalse(props, TEST_KEY)); props.put(TEST_KEY, Boolean.FALSE); assertTrue(PropertyUtils.isFalse(props, TEST_KEY)); }
@Test public void testFalse() { assertTrue(PropertyUtils.isFalse(Boolean.FALSE)); assertTrue(PropertyUtils.isFalse("false")); assertTrue(PropertyUtils.isFalse("FALSE")); assertTrue(PropertyUtils.isFalse("FaLSE")); assertFalse(PropertyUtils.isFalse(Boolean.TRUE)); assertFalse(PropertyUtils.isFalse("true")); assertFalse(PropertyUtils.isFalse("TRUE")); assertFalse(PropertyUtils.isFalse("TrUe")); assertFalse(PropertyUtils.isFalse(null)); assertFalse(PropertyUtils.isFalse("")); assertFalse(PropertyUtils.isFalse("other")); }
