Popularity：182 ℃/2025-03-02 23:43:02

In order to create a Java project to connect to StockTV's API interface, we can useHttpURLConnectionOr third-party libraryOkHttpto send HTTP requests and useJava-WebSocketLibrary to handle WebSocket connections. The following is a simple Java project structure that shows how to connect to these API interfaces.

        (response);
    }
}

8. Run the test

Run the test with the following command:

mvn test

9. Write

Finally, write oneFiles, describing the purpose, installation steps and usage methods of the project.

# StockTV API Java Client

This is a Java client for the StockTV API, providing access to global stock, forex, futures, and cryptocurrency data.

## Installation

1. Clone the repository:
   ```bash
   git clone /yourusername/
  1. Build the project:
    mvn clean install

Usage

        StockAPI stockAPI = new StockAPI(apiKey);

        try {
            String stockList = (14, 10, 1);
            (stockList);
        } catch (Exception e) {
            ();
        }
    }
}

Testing

mvn test

Summarize

This Java project structure provides a basic framework to connect to StockTV's API interface. You can extend and modify the code as needed, adding more features and tests.
