This final paper represents a web application for creating a herbarium. The document begins with a description of the technologies used, followed by an analysis of requirements and their implementation in the database and code. The backend interface was created in the IntelliJ integrated development environment with Java programming language. The goal of this application is to help the user create his own virtual or physical herbarium using plant data within the application. Each plant has information about the species, family, description and picture of the selected plant. The user can create lists of plants according to his wishes. The special feature of the application is the users ability to upload their own pictures to a personal gallery. The visual interface was created with the Java tool Thymeleaf, which uses HTML (HyperText Markup Language) and CSS (Cascading Style Sheets), and Bootstrap. MySQL database was used for data storage.
