這是你想要做什麼。我希望它能幫助你。

try{ 
       Runtime rt = Runtime.getRuntime(); 
       Process proc = rt.exec("cmd /c netstat -ano | findstr 9090"); 

       BufferedReader stdInput = new BufferedReader(new 
       InputStreamReader(proc.getInputStream())); 
       String s = null; 
       if ((s = stdInput.readLine()) != null) { 
       int index=s.lastIndexOf(" "); 
       String sc=s.substring(index, s.length()); 

       rt.exec("cmd /c Taskkill /PID" +sc+" /T /F"); 

     } 
       JOptionPane.showMessageDialog(null, "Server Stopped"); 
     }catch(Exception e){ 
       JOptionPane.showMessageDialog(null, "Something Went wrong with server"); 
      }
