### Question:
NetUtils { public static InetAddress getLocalAddress() { if (LOCAL_ADDRESS != null) return LOCAL_ADDRESS; InetAddress localAddress = getLocalAddress0(); LOCAL_ADDRESS = localAddress; return localAddress; }  static int getRandomPort(); static int getAvailablePort(); static int getAvailablePort(int port); static boolean isValidAddress(String address); static boolean isLocalHost(String host); static boolean isAnyHost(String host); static boolean isInvalidLocalHost(String host); static boolean isValidLocalHost(String host); static InetSocketAddress getLocalSocketAddress(String host, int port); static String getLocalHost(); static String filterLocalHost(String host); static InetAddress getLocalAddress(); static String getLogHost(); static String getHostName(String address); static String getIpByHost(String hostName); static String toAddressString(InetSocketAddress address); static InetSocketAddress toAddress(String address); static String toURL(String protocol, String host, int port, String path); static final String LOCALHOST; static final String ANYHOST; }### Answer:
@Test public void getLocalAddress() throws Exception { InetAddress address = InetAddress.getByName("localhost"); InetAddress localAddress = NetUtils.getLocalAddress(); System.out.println(address); System.out.println(localAddress); Assert.assertFalse(address.equals(localAddress)); }
