Java code to search all .doc and .docx files from the local system

I am working in a desktop application for a version of Windows using java. In my application, there is a requirement for searching all .doc and .docx files from MyDocuments / Documents (according to the OS) from the local system and displaying the file name and size there.

I don’t get a way to help me list all * .doc, * .docx, * .xls, * .xlsx, * .csv, * .txt, * .pdf, * .ppt, * .pptx files that are in the documents / MyDocuments.

Please give me your valuable suggestions or offer me any link that will help me write code to speed up the search and list with it name, size and type.
