### Question:
NetUtils { public static int getRandomPort() { return RND_PORT_START + RANDOM.nextInt(RND_PORT_RANGE); }  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 getRandomPort() throws Exception { int port; for (int i = 0; i < 1500; i++) { port = NetUtils.getRandomPort(); Assert.assertTrue(port >= MIN_RANDOM_PORT && port <= MAX_RANDOM_PORT); } }
