使用Java測試網絡連通性的幾種方法

使用Java測試網絡連通性的幾種方法

調用dos命令得到返回值

String command="ipconfig -all";
        String s="IPv4";
        String line = null;
        StringBuilder sb = new StringBuilder();
        Runtime runtime = Runtime.getRuntime();
        try {
        Process process = runtime.exec(command);
        BufferedReader    bufferedReader = new BufferedReader
                (new InputStreamReader(process.getInputStream()));
        
        
            while ((line = bufferedReader.readLine()) != null) {
                sb.append(line + "\n");
                if (line.contains(s)) {
                    System.out.println(line);
                }
            }
        } catch (IOException e) {
            // TODO 自動生成的 catch 塊
            e.printStackTrace();
        }
        //System.out.println(sb.toString());
