generating pdfs in java can be accomplished using several libraries, but one of the most popular and widely used libraries is **itext**. itext allows you to create and manipulate pdf documents easily. in this tutorial, we will cover the basics of generating a pdf document using the itext library.

prerequisites

1. basic knowledge of java programming.
2. java development kit (jdk) installed on your machine.
3. an ide like intellij idea, eclipse, or any text editor.

setting up

1. *download itext library:*
you can download the itext library from the maven repository or include it in your project using maven or gradle.

if you are using maven, add the following dependency to your `pom.xml`:



for gradle, add this to your `build.gradle` dependencies:



2. *create a new java project:*
set up a new java project in your ide.

sample code to generate pdf

below is a simple example of how to create a pdf document using the itext library.



explanation of the code

1. **imports**: we import necessary classes from the itext library.

2. **destination path**: configure the destination where the pdf will be created.

3. **pdfwriter**: this class is responsible for writing the pdf content to the file.

4. **pdfdocument**: represents the pdf document itself.

5. **document**: a high-level representation of the document that we can add content to.

6. **paragraph and text**: used to create and format text content in the pdf. in this example, we create a paragraph containing a styled text.

7. **closing the document**: it's essential to close the document to ensure all content is written and resources are released.

running the example

1. make sure you have added the itext library to your project.
2. copy the code into a java file (e.g., `pdfgenerationexample.java`).
3. compile and run the program.
4. after running, you should find a file named `example.pdf` in your project directory.
