java如何獲取網(wǎng)卡地址

看你獲取的是win系統(tǒng)還是linux系統(tǒng)了：

讓客戶(hù)滿(mǎn)意是我們工作的目標(biāo)，不斷超越客戶(hù)的期望值來(lái)自于我們對(duì)這個(gè)行業(yè)的熱愛(ài)。我們立志把好的技術(shù)通過(guò)有效、簡(jiǎn)單的方式提供給客戶(hù)，將通過(guò)不懈努力成為客戶(hù)在信息化領(lǐng)域值得信任、有價(jià)值的長(zhǎng)期合作伙伴，公司提供的服務(wù)項(xiàng)目有：域名注冊(cè)、網(wǎng)站空間、營(yíng)銷(xiāo)軟件、網(wǎng)站建設(shè)、伊吾網(wǎng)站維護(hù)、網(wǎng)站推廣。

java執(zhí)行操作系統(tǒng)的網(wǎng)卡地址語(yǔ)句：

獲取機(jī)器名：

[java]?view plain?copy

public?String?getLocalHostName()?{

String?hostName;

try?{

InetAddress?addr?=?InetAddress.getLocalHost();

hostName?=?addr.getHostName();

}?catch?(Exception?ex)?{

hostName?=?"";

}

return?hostName;

}

獲取IP(多個(gè)網(wǎng)卡時(shí)獲取了多個(gè)IP)：

[java]?view plain?copy

public?ListString?getNetworkAddress()?{

ListString?result?=?new?ArrayListString();

EnumerationNetworkInterface?netInterfaces;

try?{

netInterfaces?=?NetworkInterface.getNetworkInterfaces();

InetAddress?ip;

while?(netInterfaces.hasMoreElements())?{

NetworkInterface?ni?=?netInterfaces.nextElement();

EnumerationInetAddress?addresses=ni.getInetAddresses();

while(addresses.hasMoreElements()){

ip?=?addresses.nextElement();

if?(!ip.isLoopbackAddress()??ip.getHostAddress().indexOf(':')?==?-1)?{

result.add(ip.getHostAddress());

}

}

}

return?result;

}?catch?(Exception?e)?{

return?null;

}

}

JAVA如何獲得外網(wǎng)IP地址？

java獲取外網(wǎng)ip地址方法：

public class Main {

public static void main(String[] args) throws SocketException {

System.out.println(Main.getRealIp());

}

public static String getRealIp() throws SocketException {

String localip = null;// 本地IP，如果沒(méi)有配置外網(wǎng)IP則返回它

String netip = null;// 外網(wǎng)IP

EnumerationNetworkInterface netInterfaces =

NetworkInterface.getNetworkInterfaces();

InetAddress ip = null;

boolean finded = false;// 是否找到外網(wǎng)IP

while (netInterfaces.hasMoreElements() !finded) {

NetworkInterface ni = netInterfaces.nextElement();

EnumerationInetAddress address = ni.getInetAddresses();

while (address.hasMoreElements()) {

ip = address.nextElement();

if (!ip.isSiteLocalAddress()

!ip.isLoopbackAddress()

ip.getHostAddress().indexOf(":") == -1) {// 外網(wǎng)IP

netip = ip.getHostAddress();

finded = true;

break;

} else if (ip.isSiteLocalAddress()

!ip.isLoopbackAddress()

ip.getHostAddress().indexOf(":") == -1) {// 內(nèi)網(wǎng)IP

localip = ip.getHostAddress();

}

}

}

if (netip != null !"".equals(netip)) {

return netip;

} else {

return localip;

}

}

}

如何獲取局域網(wǎng)內(nèi)所有IP地址 java代碼

1.得到局域網(wǎng)網(wǎng)段，可由自己機(jī)器的IP來(lái)確定 （也可以手動(dòng)獲取主機(jī)IP-CMD-ipconfig /all）

2.根據(jù)IP類(lèi)型，一次遍歷局域網(wǎng)內(nèi)IP地址

JAVA類(lèi)，編譯之后直接運(yùn)行便可以得到局域網(wǎng)內(nèi)所有IP,具體怎樣使用你自己編寫(xiě)相應(yīng)代碼調(diào)用便可

代碼如下：：

package bean;

import java.io.*;

import java.util.*;

public class Ip{

static public HashMap ping; //ping 后的結(jié)果集

public HashMap getPing(){ //用來(lái)得到ping后的結(jié)果集

return ping;

}

//當(dāng)前線(xiàn)程的數(shù)量, 防止過(guò)多線(xiàn)程摧毀電腦

static int threadCount = 0;

public Ip() {

ping = new HashMap();

}

public void Ping(String ip) throws Exception{

//最多30個(gè)線(xiàn)程

while(threadCount30)

Thread.sleep(50);

threadCount +=1;

PingIp p = new PingIp(ip);

p.start();

}

public void PingAll() throws Exception{

//首先得到本機(jī)的IP，得到網(wǎng)段

InetAddress host = InetAddress.getLocalHost();

String hostAddress = host.getHostAddress();

int k=0;

k=hostAddress.lastIndexOf(".");

String ss = hostAddress.substring(0,k+1);

for(int i=1;i =255;i++){ //對(duì)所有局域網(wǎng)Ip

String iip=ss+i;

Ping(iip);

}

//等著所有Ping結(jié)束

while(threadCount0)

Thread.sleep(50);

}

public static void main(String[] args) throws Exception{

Ip ip= new Ip();

ip.PingAll();

java.util.Set entries = ping.entrySet();

Iterator iter=entries.iterator();

String k;

while(iter.hasNext()){

Map.Entry entry=(Map.Entry)iter.next();

String key=(String)entry.getKey();

String value=(String)entry.getValue();

if(value.equals("true"))

System.out.println(key+"--"+value);

}

}

class PingIp extends Thread{

public String ip; // IP

public PingIp(String ip){

this.ip=ip;

}

public void run(){

try{

Process p= Runtime.getRuntime().exec ("ping "+ip+ " -w 300 -n 1");

InputStreamReader ir = new InputStreamReader(p.getInputStream());

LineNumberReader input = new LineNumberReader (ir);

//讀取結(jié)果行

for (int i=1 ; i 7; i++)

input.readLine();

String line= input.readLine();

if (line.length() 17 || line.substring(8,17).equals("timed out"))

ping.put(ip,"false");

else

ping.put(ip,"true");

//線(xiàn)程結(jié)束

threadCount -= 1;

}catch (IOException e){}

}

}

}

求java獲取手機(jī)ip或者平板ip的代碼

//獲取ip地址

public String getLocalIpAddress()

{

try {

String ipv4;

ArrayListNetworkInterface nilist = Collections.list(NetworkInterface.getNetworkInterfaces());

for (NetworkInterface ni: nilist)

{

ArrayListInetAddress ialist = Collections.list(ni.getInetAddresses());

for (InetAddress address: ialist)

{

if (!address.isLoopbackAddress() InetAddressUtils.isIPv4Address(ipv4=address.getHostAddress()))

{

return ipv4;

}

}

}

} catch (SocketException ex)

{

//Log.e(LOG_TAG, ex.toString());

}

return null;

}

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 {

EnumerationNetworkInterface en = NetworkInterface.getNetworkInterfaces();

while (en.hasMoreElements()) {

NetworkInterface intf = (NetworkInterface) en.nextElement();

EnumerationInetAddress 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();

}

運(yùn)行時(shí)可調(diào)用瀏覽器打開(kāi)一個(gè)網(wǎng)頁(yè)，網(wǎng)頁(yè)地址在代碼中的java代碼怎么寫(xiě)？

網(wǎng)頁(yè)地址在代碼中的java代碼寫(xiě)法如下：

packagecom.test;

importjava.lang.reflect.Method;

//實(shí)現(xiàn)打開(kāi)瀏覽器并跳到指定網(wǎng)址的類(lèi)

publicclassBareBonesBrowserLaunch{

publicstaticvoidopenURL(Stringurl){

try{

browse(url);

}catch(Exceptione){

}

}

privatestaticvoidbrowse(Stringurl)throwsException{

//獲取操作系統(tǒng)的名字

StringosName=System.getProperty("os.name","");

if(osName.startsWith("MacOS")){

//蘋(píng)果的打開(kāi)方式

ClassfileMgr=Class.forName("com.apple.eio.FileManager");

MethodopenURL=fileMgr.getDeclaredMethod("openURL",newClass[]{String.class});

openURL.invoke(null,newObject[]{url});

}elseif(osName.startsWith("Windows")){

//windows的打開(kāi)方式。

Runtime.getRuntime().exec("rundll32url.dll,FileProtocolHandler"+url);

}else{

//UnixorLinux的打開(kāi)方式

String[]browsers={"firefox","opera","konqueror","epiphany","mozilla","netscape"};

Stringbrowser=null;

for(intcount=0;countbrowsers.lengthbrowser==null;count++)

//執(zhí)行代碼，在brower有值后跳出，

//這里是如果進(jìn)程創(chuàng)建成功了，==0是表示正常結(jié)束。

if(Runtime.getRuntime().exec(newString[]{"which",browsers[count]}).waitFor()==0)

browser=browsers[count];

if(browser==null)

thrownewException("Couldnotfindwebbrowser");

else

//這個(gè)值在上面已經(jīng)成功的得到了一個(gè)進(jìn)程。

Runtime.getRuntime().exec(newString[]{browser,url});

}

}

}

//主方法測(cè)試類(lèi)

publicstaticvoidmain(String[]args){

Stringurl="";

BareBonesBrowserLaunch.openURL(url);

}
