1.ipԴ?源码?
ipԴ??
1.得到局域网网段,可由自己机器的源码匿名聊天室源码IP来确定 (也可以手动获取主机IP-CMD-ipconfig /all)
2.根据IP类型,一次遍历局域网内IP地址
JAVA类,源码四色由弱转强指标源码编译之后直接运行便可以得到局域网内所有IP,源码开发软件为什么要源码交付具体怎样使用你自己编写相应代码调用便可
代码如下::
package bean;
import java.io.*;
import java.util.*;
public class Ip{
static public HashMap ping; //ping 后的结果集
public HashMap getPing(){ //用来得到ping后的结果集
return ping;
}
//当前线程的数量, 防止过多线程摧毁电脑
static int threadCount = 0;
public Ip() {
ping = new HashMap();
}
public void Ping(String ip) throws Exception{
//最多个线程
while(threadCount>)
Thread.sleep();
threadCount +=1;
PingIp p = new PingIp(ip);
p.start();
}
public void PingAll() throws Exception{
//首先得到本机的源码如何加大通达信源码字体IP,得到网段
InetAddress host = InetAddress.getLocalHost();
String hostAddress = host.getHostAddress();
int k=0;
k=hostAddress.lastIndexOf(“.”);
String ss = hostAddress.substring(0,源码skdj三次金叉选股源码k+1);
for(int i=1;i <=;i++){ //对所有局域网Ip
String iip=ss+i;
Ping(iip);
}
//等着所有Ping结束
while(threadCount>0)
Thread.sleep();
}
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 -n 1”);
InputStreamReader ir = new InputStreamReader(p.getInputStream());
LineNumberReader input = new LineNumberReader (ir);
//读取结果行
for (int i=1 ; i <7; i++)
input.readLine();
String line= input.readLine();
if (line.length() < || line.substring(8,源码)。equals(“timed out”))
ping.put(ip,源码“false”);
else
ping.put(ip,“true”);
//线程结束
threadCount -= 1;
}catch (IOException e){ }
}
}
}
