一、InetSocketAddress

final Socket socket = new Socket();//使用不可变对象，用于连接SocketAddress address = new InetSocketAddress("www.fortify.net", 443);try {    socket.connect(address);} catch (IOException e) {    // TODO Auto-generated catch block    e.printStackTrace();}// 连接远程主机Thread reader = new Thread() {    @Override    public void run() {        try {            byte[] buffer = new byte[512];            InputStream stream = socket.getInputStream();            socket.getInputStream().read(buffer);        } catch (Exception ex) {         }    }};reader.start();

JDK API Class InetSocketAddress

- java.net.InetSocketAddress //是Socketaddress 的子类
- ```
public class InetSocketAddressextends SocketAddress
```

This class implements an IP Socket Address (IP address + port number) It can also be a pair (hostname + port number), in which case an attempt will be made to resolve the hostname.

这个类 inetAddress是Java对IP地址的封装，代表互联网协议（IP）地址；

InetAddress对象的获取只能通过静态方法，比如根据主机名获取主机的ip地址封装对象：

If resolution fails then the address is said to be unresolved but can still be used on some circumstances like connecting through a proxy.

It provides an immutable object used by sockets for binding, connecting, or as returned values.

The wildcard is a special local IP address. It usually means "any" and can only be used for bind operations.

二、InetAddress

InetAddress是Java对IP地址的封装，代表互联网协议（IP）地址；

InetAddress对象的获取只能通过静态方法，比如根据主机名获取主机的ip地址封装对象；

InetAddress add=InetAddress.getByName("BOPZKQZ9SSY5ECY");

JDK API Class InetSocketAddress

Class InetAddress

java.net.InetAddress

public class InetAddressextends Objectimplements Serializable

This class represents an Internet Protocol (IP) address.

An IP address is either a 32-bit or 128-bit unsigned number used by IP, a lower-level protocol on which protocols like UDP and TCP are built. The IP address architecture is defined by , , , and . An instance of an InetAddress consists of an IP address and possibly its corresponding host name (depending on whether it is constructed with a host name or whether it has already done reverse host name resolution).
