The Stock Portfolio Manager is a simple and educational project designed to manage and track stock investments through a Java backend and an HTML-based frontend interface.
It provides essential CRUD (Create, Read, Update, Delete) operations, allowing users to manage stock data, view portfolio performance, and simulate investment growth in a user-friendly way.
This project demonstrates core concepts in web development, API design, and Java programming, making it perfect for learning how backend and frontend interact.
– Add, update, and delete stock records
– View portfolio performance and total value
– Organized CRUD-based backend structure
– Lightweight and easily extendable for learning or demos
– Clean HTML frontend for interaction
| Layer | Technology |
|---|---|
| Backend | Java (Maven, Spark framework) |
| Frontend | HTML, CSS |
| Architecture | CRUD API model |
| Build Tool | Apache Maven |

-
Each Stock includes data like symbol, shares, and price.
-
The Value of each stock is computed as:
value = shares × price -
The Total Portfolio Value = sum of all stock values.
-
CRUD API endpoints handle operations for adding, updating, reading, and deleting stock entries.
- Java 17 or newer
- Maven (included wrapper:
mvnw) - Any browser for frontend access

By building this project, you’ll understand:
- How CRUD APIs work in a Java environment
- The connection between backend logic and frontend interfaces
- Managing data models and web requests in a full-stack workflow
