manpreet Best Answer 2 years ago

I have some metadata file sample.json. Now i want to classify my metadata file using java.

This is my metadata file:

{"Author: ":null,"Title: ":" Syllabus","File name: ":" Syllabus Exp.htm"}
{"Author: ":null,"Title: ":" sample Syllabus","File name: ":" Syllabus.htm"}
{"Author: ":null,"Title: ":null,"File name: ":"sample.pdf"}.

please suggest me how to classify above metadata file.

thanks.
