## Initializing the client
You can initialize a Dapr client as so:

```java
DaprClient client = new DaprClientBuilder().build()
```

This will connect to the default Dapr gRPC endpoint `localhost:50001`.


#### Environment variables:

##### Dapr Sidecar Endpoints
You can use the standardized `DAPR_GRPC_ENDPOINT` and `DAPR_HTTP_ENDPOINT` environment variables to
specify a different gRPC endpoint. When these variables are set, the client will automatically use them to connect to the Dapr sidecar.

The legacy environment variables `DAPR_HTTP_PORT` and `DAPR_GRPC_PORT` are still supported, but `DAPR_GRPC_ENDPOINT` and `DAPR_HTTP_ENDPOINT` take precedence.

##### Dapr API Token
If your Dapr instance is configured to require the `DAPR_API_TOKEN` environment variable, you can
set it in the environment and the client will use it automatically.
You can read more about Dapr API token authentication [here](https://docs.dapr.io/operations/security/api-token/).



## Building blocks

The Java SDK allows you to interface with all of the [Dapr building blocks]({{< ref building-blocks >}}).
