Java如何執(zhí)行cmd命令

//一般的執(zhí)行方法，有時執(zhí)行exe會卡在那  stmt要執(zhí)行的命令
  public static void executive(String stmt) throws IOException, InterruptedException {
    Runtime runtime = Runtime.getRuntime(); //獲取Runtime實例
    //執(zhí)行命令
    try {
      String[] command = {"cmd", "/c", stmt};
      Process process = runtime.exec(command);
      // 標準輸入流（必須寫在 waitFor 之前）
      String inStr = consumeInputStream(process.getInputStream());
      // 標準錯誤流（必須寫在 waitFor 之前）
      String errStr = consumeInputStream(process.getErrorStream());
      new ProcessClearStream(process.getInputStream(), "INFO").start();
      new ProcessClearStream(process.getErrorStream(), "ERROR").start();
      int proc = process.waitFor();
      InputStream errorStream = process.getErrorStream(); //若有錯誤信息則輸出
      if (proc == 0) {
        System.out.println("執(zhí)行成功");
      } else {
        System.out.println("執(zhí)行失敗" + errStr);
      }
    } catch (IOException | InterruptedException e) {
      e.printStackTrace();
    }
  }

　　/**
   * 消費inputstream，并返回
   */
  public static String consumeInputStream(InputStream is) throws IOException {
    BufferedReader br = new BufferedReader(new InputStreamReader(is,"GBK"));
    String s;
    StringBuilder sb = new StringBuilder();
    while ((s = br.readLine()) != null) {
      System.out.println(s);
      sb.append(s);
    }
    return sb.toString();
  }

//這個方法比第一個好，執(zhí)行時不會卡 stmt要執(zhí)行的命令
  public static void aaa(String stam){
    BufferedReader br = null;
    try {
      File file = new File("D:\\daemonTmp");
      File tmpFile = new File("D:\\daemonTmp\\temp.tmp");//新建一個用來存儲結(jié)果的緩存文件
      if (!file.exists()){
        file.mkdirs();
      }
      if(!tmpFile.exists()) {
        tmpFile.createNewFile();
      }
      ProcessBuilder pb = new ProcessBuilder().command("cmd.exe", "/c", stam).inheritIO();
      pb.redirectErrorStream(true);//這里是把控制臺中的紅字變成了黑字，用通常的方法其實獲取不到，控制臺的結(jié)果是pb.start()方法內(nèi)部輸出的。
      pb.redirectOutput(tmpFile);//把執(zhí)行結(jié)果輸出。
      pb.start().waitFor();//等待語句執(zhí)行完成，否則可能會讀不到結(jié)果。
      InputStream in = new FileInputStream(tmpFile);
      br= new BufferedReader(new InputStreamReader(in));
      String line = null;
      while((line = br.readLine()) != null) {
        System.out.println(line);
      }
      br.close();
      br = null;
      tmpFile.delete();//卸磨殺驢。
      System.out.println("執(zhí)行完成");
    } catch (Exception e) {
      e.printStackTrace();
    } finally {
      if(br != null) {
        try {
