You should use a PDF parser for that. Check out this list of open source PDF libraries for Java .

SOme PDF files contain PDF structured text (http://www.jpedal.org/PDFblog/2010/09/the-easy-way-to-discover-if-a-pdf-file-contains-structured-content/). If they do not, it is down to the heuristics of the parser to guess this and add structure.
