Poi generates word files, and poi generates word files.

I. Introduction
For poi, You can process word, excel, and ppt. Word currently has two file formats: doc suffix and docx suffix. Versions earlier than 2007 are suffixed with doc. This format of poi uses HWPF for processing. HWPF can also provide limited support for file processing in the old word6 and word95 formats. 2007 (including) is followed by the docx suffix, and poi uses XWPF for processing. HWPF and XWPF have similar features, but currently they do not share interfaces.
HWPF and XWPF can be described as "moderate functionality ". For some examples, the management of Text Extraction provides strong support. For other LEs, the support is limited or incomplete and requires in-depth research on low-level code. Error detection has been removed. All files with incorrect format may be created.
HWPF is included in the poi-scratchpad-XXX.jar package, while XWPF is included in the poi-ooxml-XXX.jar package. We can add these packages to classpath as needed. HWPF and XWPF Web site: http://poi.apache.org/document/index.html.
