# v2 API Java Code Example

> \[!WARNING]
>
> To access all the latest features and upcoming developments, please see our [v3 API](/docs/sendgrid/api-reference). For assistance with transitioning, refer to our [migration guide](/docs/sendgrid/for-developers/migration-guides/v2-to-v3-api).

> \[!NOTE]
>
> We recommend using SendGrid Java, our client library, [available on GitHub](https://github.com/sendgrid/sendgrid-java), with full documentation.

> \[!NOTE]
>
> The library does not officially support the V2 API, but you can use V2 with an older version of the library. For more information, see [Continue Using V2 in Java](https://github.com/sendgrid/sendgrid-java/blob/main/TROUBLESHOOTING.md#v2).

## Using SendGrid's Java Library

```java
// using SendGrid's Java Library
// https://github.com/sendgrid/sendgrid-java
import com.sendgrid.*;

public class SendGridExample {
  public static void main(String[] args) {
    SendGrid sendgrid = new SendGrid("SENDGRID_APIKEY");

    SendGrid.Email email = new SendGrid.Email();

    email.addTo("test@sendgrid.com");
    email.setFrom("you@example.com");
    email.setSubject("Sending with SendGrid is Fun");
    email.setHtml("and easy to do anywhere, even with Java");

    SendGrid.Response response = sendgrid.send(email);
  }
}
```
