Method

booleanavailable(final int port)
available 
ServerSocket serverSocket = null;
try {
    serverSocket = new ServerSocket(port);
    serverSocket.setReuseAddress(true);
    return true;
} catch (final IOException e) {
} finally {
    if (serverSocket != null) {
...
booleanavailable(int port)
Checks to see if a specific port is available(Bind is not called). 
ServerSocket ss = null;
DatagramSocket ds = null;
try {
    ss = new ServerSocket(port);
    ss.setReuseAddress(true);
    ds = new DatagramSocket(port);
    ds.setReuseAddress(true);
    return true;
...
booleanavailable(int port)
Checks if a port is available by attempting to create a socket 
try {
    Socket ignored = new Socket("localhost", port);
    ignored.close();
    return false;
} catch (IOException ignored) {
    return true;
booleanavailable(int port)
available 
Socket s = null;
try {
    s = new Socket("localhost", port);
    return false;
} catch (IOException e) {
    return true;
} finally {
    if (s != null) {
...
booleanavailable(int port)
available 
if (port < MIN_PORT_NUMBER || port > MAX_PORT_NUMBER) {
    throw new IllegalArgumentException("Invalid start port: " + port);
ServerSocket ss = null;
DatagramSocket ds = null;
try {
    ss = new ServerSocket(port);
    ss.setReuseAddress(true);
...
intavailable_port()
availablport 
return available_port(0);
ServerSocketavailableAndReturn(int MIN_PORT_NUMBER, int MAX_PORT_NUMBER)
available And Return 
boolean bindSuccess = false;
ServerSocket ss = null;
AtomicInteger start = new AtomicInteger(MIN_PORT_NUMBER);
while (!bindSuccess && start.get() < MAX_PORT_NUMBER) {
    try {
        ss = new ServerSocket(start.get());
        ss.setReuseAddress(true);
        bindSuccess = true;
...
intavailablePort()
Will determine the available port 
ServerSocket s = null;
try {
    s = new ServerSocket(0);
    s.setReuseAddress(true);
    return s.getLocalPort();
} catch (Exception e) {
    throw new IllegalStateException("Failed to discover available port.", e);
} finally {
...

ServerSocket ss = null;
DatagramSocket ds = null;
try {
    ss = new ServerSocket(port);
    ss.setReuseAddress(true);
    ds = new DatagramSocket(port);
    ds.setReuseAddress(true);
    return true;
...
booleanavailablePort(int pPort)
Method that checks whether or not a port is available on the host computer. 
ServerSocket newlySocket = null;
boolean response = false;
try {
    newlySocket = new ServerSocket(pPort);
    response = true;
} catch (IOException e) {
    response = false;
} finally {
