Build me a small Java console application to read PDF -- 2

1) Create a pdf parser which we will read data from the pdf and store in the model attached. 2) The pdf contains question text (optional images, equations, formulas), choices, correct answer, complexity etc. Sample PDF has been attached. 3) The question may contain superscript and subscript elements. These should be preserved while parsing. 4) New question may begin with Ques, Q, Question etc. (like ques 1, q1 etc.) 5) The image should be copied to a directory in the machine and its path should be embedded in the question text. Some possible examples: - Q1 What is the name of the below painting? <img src='path_to_image'> Hint:painted by Da Vinci - Ques2 (a+b)²=? In example 1, path_to_image is the path on machine where image is stored from the pdf. In example 2, sup means superscript to infer the formula (a+b) whole squared. Preferably using PDFBox or any other open source library.
