### Question:
L2pLogger extends Logger implements NodeObserver { public static L2pLogger getInstance(Class<?> cls) throws ClassCastException { return getInstance(cls.getCanonicalName()); } protected  L2pLogger(String name, String resourceBundleName); synchronized void printStackTrace(Throwable e); static void setGlobalLogDirectory(String directory); synchronized void setLogDirectory(String directory); static void setGlobalLogfilePrefix(String prefix); synchronized void setLogfilePrefix(String prefix); static void setGlobalConsoleLevel(Level level); synchronized void setConsoleLevel(Level level); static void setGlobalLogfileLevel(Level level); synchronized void setLogfileLevel(Level level); @Override void log(LogRecord record); @Deprecated static void logEvent(MonitoringEvent event, String message); @Deprecated static void logEvent(MonitoringEvent event, Agent actingUser, String message); @Deprecated static void logEvent(Object from, MonitoringEvent event, String message); @Deprecated static void logEvent(Object from, MonitoringEvent event, String message, Agent serviceAgent,
			Agent actingUser); @Deprecated static void logEvent(Node node, Object from, MonitoringEvent event, String message, Agent serviceAgent,
			Agent actingUser); void log(MonitoringEvent event); void log(MonitoringEvent event, String remarks); void log(MonitoringEvent event, String sourceAgentId, String destinationAgentId, String remarks); @Deprecated @Override void log(Long timestamp, MonitoringEvent event, String sourceNode, String sourceAgentId,
			String destinationNode, String destinationAgentId, String remarks); static Formatter getGlobalConsoleFormatter(); static Formatter getGlobalLogfileFormatter(); static L2pLogger getInstance(Class<?> cls); static L2pLogger getInstance(String name); static final String GLOBAL_NAME; static final int DEFAULT_LIMIT_BYTES; static final int DEFAULT_LIMIT_FILES; static final String DEFAULT_ENCODING; static final String DEFAULT_LOG_DIRECTORY; static final String DEFAULT_LOGFILE_PREFIX; static final Level DEFAULT_CONSOLE_LEVEL; static final Level DEFAULT_LOGFILE_LEVEL; static final Level DEFAULT_OBSERVER_LEVEL; static final SimpleDateFormat DEFAULT_DATE_FORMAT; }### Answer:
@Test public void testParent2() { L2pLogger logger = L2pLogger.getInstance(L2pLoggerTest.class.getName()); assertTrue(logger instanceof L2pLogger); Logger parent = logger.getParent(); assertNotNull(parent); assertTrue(parent instanceof L2pLogger); }
