Java調win控制檯獲取佔用端口的程序名

常常在調用bind方法的時候程序被佔用了。如何查找是哪一個程序佔用的呢？代碼以下：

private void bindCheck(int port){
        Runtime run = Runtime.getRuntime();
        try {
            Process process = run.exec("netstat -ano");

            InputStream input = process.getInputStream();
            InputStream inputE = process.getErrorStream();
            BufferedReader reader = new BufferedReader(new InputStreamReader(input,"GB2312"));
            String szline;
            String pid = null;
            while ((szline = reader.readLine()) != null) {
                if(szline.indexOf(":"+port)>0){
                    pid = szline.split("\\s+")[szline.split("\\s+").length - 1];
                }
            }
            reader.close();
            reader = new BufferedReader(new InputStreamReader(inputE,"GB2312"));
            while ((szline = reader.readLine()) != null) {
                System.out.println(szline);
            }
            reader.close();
            process.waitFor();
            process.destroy();

            if(pid != null){
                process = run.exec("tasklist");
                input = process.getInputStream();
                inputE = process.getErrorStream();
                reader = new BufferedReader(new InputStreamReader(input,"GB2312"));
                while ((szline = reader.readLine()) != null) {
                    if(szline.indexOf(pid)>0){
                        System.out.println("[ERROR] Bind error!\nThis pid occupies the port "+port+"\n"+Arrays.toString(szline.split("\\s+")));
                    }
                }
                reader.close();

                reader = new BufferedReader(new InputStreamReader(inputE,"GB2312"));
                while ((szline = reader.readLine()) != null) {
                    System.out.println(szline);
                }
                reader.close();
                process.waitFor();
                process.destroy();
            }else{
                System.out.println("No process occupies port "+ port);
            }


        } catch (Exception e) {
            e.printStackTrace();
        }
    }
