Add Lists to PDF in Java
There are two types of lists commonly seen in electronic document: ordered list and unordered list. An ordered list is a collection of related items with a special order or sequence, which are usually organized by different schemes of numbers. Items in an unordered list have no obvious order and are usually organized by bullets.
Spire.PDF for Java provides the PdfSortedList class and PdfUnsortedList class for developers to create these two types of lists respectively. In the following sections, I am going to introduce how to add a numbered list, a bulleted list and a nested listed in PDF by using this library.
If you're creating a Maven project, you can easily import the jar in your application using the following configurations. For non-Maven projects, download the jar file from this link and add it as a dependency in your application.
