### Question:
LoggerFactory { public static String getSimpleClassName(String className) { String[] parts = className.split("\\."); if (parts.length <= 1) { return className; } else { return parts[parts.length - 1]; } } private  LoggerFactory(); static Logger getLogger(Class<?> clazz); static Logger getLogger(String className); static String getSimpleClassName(String className); static final String LOG_TYPE_SYSTEM_PROPERTY; }### Answer:
@Test public void testGetSimpleClassName() { String first = "foo"; String name = LoggerFactory.getSimpleClassName(first); assertEquals(first, name); String second = "bar"; String className = first + "." + second; name = LoggerFactory.getSimpleClassName(className); assertEquals(second, name); }
