Java InetSocketAddress 类说明

摘要: 学会查JDK api 感谢 OSChina 提供的 在线 查阅方法 http://tool.oschina.net/apidocs/apidoc?api=jdk_7u4

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.lang.Object

java.net.SocketAddress

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.lang.Object

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 RFC 790: Assigned Numbers, RFC 1918: Address Allocation for Private Internets, RFC 2365: Administratively Scoped IP Multicast, and RFC 2373: IP Version 6 Addressing Architecture. 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).

Direct Known Subclasses:

Inet4Address, Inet6Address

All Implemented Interfaces:

Serializable
