It can be used to parse encrypted documents too if the password is specified as an argument. It extracts the contents of a PDF Document stored within paragraphs, strings, and tables (without invoking tabular boundaries). PDFParser Java provides an in-built package that provides a class PDFParser, which parses the contents of PDF documents. The specified text can be retrieved using the method ContentHandlerDecorator.toString() provided by the parent class. It is inherited from the parent class ContentHandlerDecorator in Java. The following classes are used in the extraction of the content :īod圜ontentHandler is an in-built class that creates a handler for the text, which writes these XHTML body character events and stores them in an internal string buffer. Java supports multiple in-built classes and packages to extract and access the content from a PDF document.
