### Question:
PropertyUtils { public static boolean getBoolean(String key) { String value = properties.getProperty(key.trim()); if (value == null) { return false; } return Boolean.parseBoolean(value); } private  PropertyUtils(); static String getString(String key, String defaultVal); static String getString(String key); static int getInt(String key); static int getInt(String key, int defaultValue); static boolean getBoolean(String key); static Boolean getBoolean(String key, boolean defaultValue); static long getLong(String key, long defaultVal); static long getLong(String key); static double getDouble(String key, double defaultVal); T getEnum(String key, Class<T> type,
                                         T defaultValue);  }### Answer:
@Test public void testGetBoolean() { Boolean result = PropertyUtils.getBoolean("test.true"); assertTrue(result); result = PropertyUtils.getBoolean("test.false"); assertFalse(result); }
