ipaction.java

基于JAVA的简单扫描器

package Scanner;

import java.io.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
class ipAction implements ActionListener
{
 public static int flag2=0;
public void actionPerformed (ActionEvent a) 
{ String ipstart;
  String ipend;	
  String substr; 
  char[] strs;
  //本程序只能扫描一个D段.
 int ipth,i,j;
 ipstart=ThreadScan.startip.getText().trim();
 ipend=ThreadScan.endip.getText().trim();
 ipth=Integer.parseInt(ThreadScan.ipthread.getText());
 ThreadScan.Result1.append("\n在线主机:\n");
 ThreadScan.status1.setEnabled(true);
 
 strs=ipstart.toCharArray();
 i=0;j=0;
 while(i!=3)
 {  if(strs[j]=='.') i++;
    j++;
 	}
 ipThread.ipbase=ipstart.substring(0,j);
 ipThread.last1=Integer.parseInt(ipstart.substring(j));
 ipThread.last2=Integer.parseInt(ipend.substring(j));
 ipThread.threadip=ipth;
 //System.out.println(ipThread.threadip);
 
 for(i=0;i<ipth;i++)
 //Create i thread;
 
 {
 	new ipThread("IP" + i,i).start();
 	
 }
  flag2=0;
}	
	
	}
