HTML to PDF
You can also convert HTML to PDF using Java. This is done by using the Java API for HTML to PDF (jAHT). The Java API for HTML to PDF provides a high-level API for converting documents containing HTML and CSS markup into Portable Document Format (PDF) files.
The jAHT is available as part of the JAXP standard and implements the “content handler” model that was introduced with version 1.3 of the Apache OpenOffice application.
Dynamic Data and Interactivity
You’re probably familiar with HTML5 and CSS, but there are other ways to create games. For example, you can use the canvas API to draw directly in your browser. This is a great way to make games that run on any device and don’t require constant internet access or an app store submission process.
Desktop Apps for Windows, MacOS or Linux
Smartwatches or Other IoT Devices
It’s also possible to create an app that is connected to the internet and will run on multiple devices at once instead of just one specific device like a smartwatch would run only on your wrist while wearing it.
