### Question:
SimpleKeyFile implements SecureKeyStore, Configurable, LogSource { @Override public Logger getLogger () { return logger; } SimpleKeyFile();  SimpleKeyFile(String keyFileName); void init(String keyFileName); @Override void setLogger(Logger logger, String realm); @Override Logger getLogger(); @Override String getRealm(); @Override void setConfiguration(Configuration cfg); @Override synchronized SecureKey getKey(String alias); @Override synchronized void setKey(String alias, SecureKey secureKey); String getProperty(String alias, String subName); void setProperty(String alias, String subName, String value); @Override Map<String, SecureKey> getKeys();  }### Answer:
@Test public void testGetLogger() throws Throwable { Logger logger = Logger.getLogger("testSimpleKeyFileName"); SimpleKeyFile simpleKeyFile = new SimpleKeyFile(); simpleKeyFile.setLogger(logger, "testSimpleKeyFileRealm"); Logger result = simpleKeyFile.getLogger(); assertSame(logger, result, "result"); }
