Question

我正在尝试创建一个新的文件目录，但函数mkdir()不起作用，mkdirs()。

这是我的代码：

...
  while (leitor.hasNext()){
      String [] plv = LerPalavras(tamMem, leitor);
      Arrays.sort(plv);
      String nomeTemp = "/temp/temp" + contador + ".txt"; // I need to create this directory
      try{
        escritor = new FileWriter(nomeTemp);
        for (int i = 0; i < tamMem; i++) {
          escritor.write(plv[i] + " ");
        }
        escritor.close();
      } catch (IOException e){
        System.out.println(e.getMessage());
      }
      contador++;
    }
...

编辑：我进行了编辑，现在它正在运作！

File pastaTemp = new File("/temp/temp");
    pastaTemp.mkdirs();

    while (leitor.hasNext()){
      String [] plv = LerPalavras(tamMem, leitor);
      Arrays.sort(plv);
      File arqTemp = new File (pastaTemp, contador + ".txt");
      try{
        escritor = new FileWriter(arqTemp);
        for (int i = 0; i < tamMem; i++) {
          escritor.write(plv[i] + " ");
        }
        escritor.close();
      } catch (IOException e){
        System.out.println(e.getMessage());
      }
      contador++;
    }

尝试分两步完成。首先，如有必要，调用import base64 imgdata = base64.b64decode(new_string) filename = 'image.jpg' # I assume you have a way of picking unique filenames with open(filename, 'wb') as f: f.write(imgdata)创建整个目录结构，然后创建传递给try: convertedFileString = fstring.replace('-', '+').replace('_','/').replace(',','=') imgdata = base64.b64decode(new_string) # I assume you have a way of picking unique filenames with open(filename, 'wb') as f: s3 = boto3.resource('s3') bucket = s3.Bucket('ag-grid') bucket.put_object(Key=filename, Body=f) except Exception as e: return { 'statusCode': 500, 'body': str(e) }的文件：

File.mkdirs()

如何在Java中创建目录？
