In this article, we’ll see how to edit the content of an existing PDF file in Java. First, we’ll just add new content. Then, we’ll focus on removing or replacing some pre-existing content.
We’ll use the iText7 library to add content to the PDF file. Later on, we’ll use the pdfSweepadd-on to remove or replace content. Note that iText is licensed under AGPL, which might limit the distribution of a commercial application: iText License Model. First, let’s add these dependencies to our pom.xml:
Let’s understand the steps for handling our PDF with iText7: 1. First, we open a PdfReader to read the content of the source file. This throws an IOExceptionif an error occurs at any time while reading the file. 2. Then, we open a PdfWriter to the destination file. If this file doesn’t exist or can’t be created, a FileNotFoundExceptionis thrown. 3....
Let’s now see how we can remove content from the PDF file. To keep things simple, we’ll write another main()method. Our source PDF file will be the baeldung-modified.pdf file and the destination will be a new baeldung-cleaned.pdf file. We’ll work directly on the PdfDocumentobject. From now on, we’ll use iText’s pdfSweep add-on.
In this section, we’ll do the same work as earlier, except that we’ll replace the former text with a new text instead of only erasing it. For more clarity, we’ll use a new main() method again. Our source file will be the baeldung-modified.pdf file. Our destination file will be a new baeldung-fixed.pdffile. Earlier we saw that the removed text was o...

Apr 2, 2024 · This article will discuss different ways to create a mutable, unmodifiable, and immutable empty set in Java. Mutable Sets supports modification operations such as add, remove, and clear on it. Unmodifiable Sets are “read-only” wrappers over other sets. They do not support add, remove, and clear operations, but their underlying set can be ...
Immutable objects are constructed once, in a consistent state, and can be safely shared. Will fail if mandatory attributes are missing. Cannot be sneakily modified when passed to other code. Immutable objects are naturally thread-safe and can therefore be safely shared among threads. No excessive copying.
