### Question:
FilteredLogger { public boolean isLoggable() { return this.isLoggable(FilteredLogger.DEFAULT_LOG_LEVEL); } protected  FilteredLogger(final String className); static String filterSecrets(final String in); static FilteredLogger getFilteredLogger(final String className); void entering(final String sourceClass, final String sourceMethod); void entering(final String sourceClass, final String sourceMethod, final Object param); void entering(final String sourceClass, final String sourceMethod, final Object[] params); ResourceBundle getResourceBundle(); boolean isLoggable(); boolean isLoggable(final Level logLevel); void log(final Level logLevel, final String msg, final Object param); void log(final Level logLevel, final String msg, final Object[] params); void log(final Level logLevel, final String msg, final Throwable thrown); void log(final String msg, final Object param); void log(final String msg, final Object[] params); void log(final String msg, final Throwable thrown); void exiting(final String sourceClass, final String sourceMethod); void exiting(final String sourceClass, final String sourceMethod, final Object result);  }### Answer:
@Test public void testFilteredLogger_1() throws Exception { final String className = ""; final FilteredLogger result = new FilteredLogger(className); Assert.assertNotNull(result); Assert.assertEquals(false, result.isLoggable()); }
