### Question:
NetUtils { public static InetSocketAddress getLocalSocketAddress(String host, int port) { return isInvalidLocalHost(host) ? new InetSocketAddress(port) : new InetSocketAddress(host, port); }  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 getLocalSocketAddress() throws Exception { InetSocketAddress add1 = NetUtils.getLocalSocketAddress("127.0.0.1", 11111); InetSocketAddress add2 = NetUtils.getLocalSocketAddress("localhost", 11111); InetSocketAddress add3 = NetUtils.getLocalSocketAddress("192.168.0.1", 11111); Assert.assertTrue(add1.equals(add2)); Assert.assertTrue(!add1.equals(add3)); }
