java本地ip地址

⑴ java如何獲取本地計算機的IP地址和主機名

可以使用 InetAddress.getLocalHost()，代碼如下：

importjava.net.*;

publicclassApp{

	publicstaticvoidmain(String[]args)throwsUnknownHostException{
		
		InetAddresslocal=InetAddress.getLocalHost();
		
		System.out.println("計算機名："+local.getHostName());
		System.out.println("IP："+local.getHostAddress());
		
	}
}

⑵ java怎麼獲取ip地址

java獲取ip地址
public static void main(String[] args) { try { // 獲取計算機名 String name = InetAddress.getLocalHost().getHostName(); // 獲取IP地址 String ip = InetAddress.getLocalHost().getHostAddress(); System.out.println("計算機名："+name); System.out.println("IP地址："+ip); } catch (UnknownHostException e) { System.out.println("異常：" + e); e.printStackTrace(); } }

⑶ 如何用java獲取本地ip地址

import java.net.Inet4Address;
import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.util.ArrayList;
import java.util.Enumeration;
import java.util.List;

public class IpAddress {
public static String find() {
List<String> ips = new ArrayList<String>();
// 返回所有網路介面的一個枚舉實例
Enumeration<?> allNetInterfaces = null;
try {
allNetInterfaces = NetworkInterface.getNetworkInterfaces();
} catch (SocketException e) {
e.printStackTrace();
}
InetAddress ip = null;
while (allNetInterfaces.hasMoreElements()) {
NetworkInterface netInterface = (NetworkInterface) allNetInterfaces.nextElement();
Enumeration<InetAddress> addresses = netInterface.getInetAddresses();
while (addresses.hasMoreElements()) {
// 獲得當前網路介面
ip = (InetAddress) addresses.nextElement();
if (ip != null && ip instanceof Inet4Address && ip.getHostAddress().indexOf(".") != -1) {
ips.add(ip.getHostAddress());
}
}
}
if (ips.size() == 1) {
return ips.get(0);
} else {
for (String ipa : ips) {
if (!"127.0.0.1".equals(ipa)) {
return ipa;
}
}
}
return MacAddress.find();
}
}

⑷ java如何查詢本機ip地址和mac地址

Java中可以使用程序來獲取本地ip地址和mac地址，使用InetAddress這個工具類，示例如下：

importjava.net.*;
publicclassNetInfo{
publicstaticvoidmain(String[]args){
newNetInfo().say();
}
publicvoidsay(){
try{
InetAddressi=InetAddress.getLocalHost();
System.out.println(i);//計算機名稱和IP
System.out.println(i.getHostName());//名稱
System.out.println(i.getHostAddress());//只獲得IP
}
catch(Exceptione){e.printStackTrace();}
}
}

也可以通過命令行窗口來查看本地ip和mac地址，輸入命令：ipconfig。

⑸ java中獲取本地IP地址

方法如下：
方法一，使用CMD命令：
public static String getLocalIPForCMD(){
StringBuilder sb = new StringBuilder();
String command = "cmd.exe /c ipconfig | findstr IPv4";
try {
Process p = Runtime.getRuntime().exec(command);
BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line = null;
while((line = br.readLine()) != null){
line = line.substring(line.lastIndexOf(":")+2,line.length());
sb.append(line);
}
br.close();
p.destroy();
} catch (IOException e) {
e.printStackTrace();
}
return sb.toString();
}
方法二，使用Java方法：
public static String getLocalIPForJava(){
StringBuilder sb = new StringBuilder();
try {
Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces();
while (en.hasMoreElements()) {
NetworkInterface intf = (NetworkInterface) en.nextElement();
Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses();
while (enumIpAddr.hasMoreElements()) {
InetAddress inetAddress = (InetAddress) enumIpAddr.nextElement();
if (!inetAddress.isLoopbackAddress() && !inetAddress.isLinkLocalAddress()
&& inetAddress.isSiteLocalAddress()) {
sb.append(inetAddress.getHostAddress().toString()+"\n");
}
}
}
} catch (SocketException e) { }
return sb.toString();
}

⑹ Java如何獲取本地連接中配置的IP地址

publicstaticvoidmain(String[]args)
{
try
{
//獲取計算機名
Stringname=InetAddress.getLocalHost().getHostName();
//獲取IP地址
Stringip=InetAddress.getLocalHost().getHostAddress();
System.out.println("計算機名："+name);
System.out.println("IP地址："+ip);
}
catch(UnknownHostExceptione)
{
System.out.println("異常："+e);
e.printStackTrace();
}
}

⑺ java怎麼獲取本地ip地址

Jva獲取本地的IP地址，這個你就需要到你的手機的網路客戶端裡面進行設置了，這個話都是可以去查看的。
