How to extract all properties (Paper Size, Format, Producer) of a PDF using java program

I am able to extract PDF properties using java code as below: But i am confused how to get [Format like "PDF1.3" and page Size like"A4, Portrait (210 × 297 mm)"] properties using java code.

System.out.println(file.getName());
PdfReader reader = new PdfReader(file.toString());
HashMap<String, String> info = reader.getInfo(); 
char info1=reader.getPdfVersion();
byte[] b1 = reader.getMetadata();
System.out.println(info);
System.out.println(info1);

I have tried PDFbox API also, but i cant find the method for the same, Is it possible to fetch the following properties using java (i am using ubuntu)

You can get document information using PDDocument class in PDFBox api. PDDocumentInformation is used to retrieve author, version, created date, updated date, etc features.

PDDocument doc = PDDocument.load(new File(filePath));
PDDocumentInformation info = doc.getDocumentInformation();
String author = info.getAuthor();
int pages = doc.getNumberOfPages();
// String creator  = info.getCreator();
Calendar calendar = info.getCreationDate();
System.out.println("Author : " + author);
System.out.println("Created : " + new SimpleDateFormat("dd-MM-yyyy hh:mm:ss aa").format(calendar.getTimeInMillis()));
System.out.println("Total Pages : " + pages);
if(pages > 0) {
    float width = doc.getPage(0).getMediaBox().getWidth();
    float height = doc.getPage(0).getMediaBox().getHeight();
    System.out.println("Page 0 size : " + width + " * " + height);
} else {
    System.err.println("No pages.");
}

Edit
