Batch Scan prototype in Java call Nmap for host detection

In Java, by calling Runtime , this class can execute other executable programs, return a process after execution, take advantage of the class of process we can get the echo of program execution, so call in Java the principle of the host detection of nmap is very clear. By passing the path to the function Nmap and the commands we need to execute

/** *  call Nmap to scan  *  @param  nmapdir nmap path  *  @param  command  Execute command  *  *  @return   perform echo  * */public  string getreturndata (String nmapdir,string command) {Process process = null ; Stringbuffer stringbuffer = new stringbuffer ();try {process =  Runtime.getruntime (). EXEC (nmapdir +  " "  + command); SYSTEM.OUT.PRINTLN ("Please wait a moment ... "); Bufferedreader reader = new bufferedreader (New inputstreamreader ( Process.getinputstream (), "UTF-8")); String line = null;while ((Line = reader.readline ())  != null) { Stringbuffer.append (line +  "\ n");}}  catch  (ioexception e)  {e.printstacktrace ();} Return stringbuffer.tostring ();} 

Test:

NmapTest1 nmapTest1 = new NmapTest1 (); String str = nmaptest1.getreturndata ("D:\\nmap\\nmap.exe", "-ss-p0-a-V-www.zifangsky.cn"); System.out.println (str);

return Result:

Please wait a moment ...
