    English Answer:
    Apache POI is a Java library that provides support for reading and writing Microsoft Office formats. It can be used to read and write Excel, Word, PowerPoint, and other Office file formats. POI is a pure Java library, which means that it can be used on any platform that supports Java.
    To use POI to read an Office file, you first need to create a FileInputStream object for the file. Then, you can use the appropriate POI class to read the file. For example, to read an Excel file, you would use the HSSFWorkbook class.
    Once you have read the file, you can access the data in the file using the POI API. For example, to get the value of a cell in an Excel file, you would use the getCellValue() method of the HSSFCell class.
    To write an Office file, you first need to create a FileOutputStream object for the file. Then,
you can use the appropriate POI class to write the file. For example, to write an Excel file, you would use the HSSFWorkbook class.
    Once you have written the file, you can close the FileOutputStream object.
    Chinese Answer:
    Apache POI是一个Java库，它提供了对Microsoft Office格式的读写支持。它可以用来读写Excel，Word，PowerPoint和其他Office文件格式。POI是一个纯粹的Java库，这意味着它可以在任何支持Java的平台上使用。
    要使用POI读取Office文件，首先需要为该文件创建一个FileInputStream对象。然后，您可以使用适当的POI类来读取文件。例如，要读取Excel文件，则可以使用HSSFWorkbook类。
inputtypefile不上传文件    读取文件后，可以使用POI API访问文件中的数据。例如，要获取Excel文件中的单元格值，可以使用HSSFCell类的getCellValue()方法。
    要写入Office文件，首先需要为文件创建一个FileOutputStream对象。然后，您可以使用适当的POI类来写入文件。例如，要写入Excel文件，则可以使用HSSFWorkbook类。
    写完文件后，可以关闭FileOutputStream对象。
