The following code examples show how to use `CreateFilter`.

------
#### [ Java ]

**SDK for Java 2.x**  
 There's more on GitHub. Find the complete example and learn how to set up and run in the [AWS Code Examples Repository](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/javav2/example_code/personalize#code-examples). 

```
    public static String createFilter(PersonalizeClient personalizeClient,
            String filterName,
            String datasetGroupArn,
            String filterExpression) {
        try {
            CreateFilterRequest request = CreateFilterRequest.builder()
                    .name(filterName)
                    .datasetGroupArn(datasetGroupArn)
                    .filterExpression(filterExpression)
                    .build();

            return personalizeClient.createFilter(request).filterArn();
        } catch (PersonalizeException e) {
            System.err.println(e.awsErrorDetails().errorMessage());
            System.exit(1);
        }
        return "";
    }
```

#### [ JavaScript ]

**SDK for JavaScript (v3)**  
 There's more on GitHub. Find the complete example and learn how to set up and run in the [AWS Code Examples Repository](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/javascriptv3/example_code/personalize#code-examples). 

```
// Get service clients module and commands using ES6 syntax.
import { CreateFilterCommand } from "@aws-sdk/client-personalize";
import { personalizeClient } from "./libs/personalizeClients.js";
// Or, create the client here.
// const personalizeClient = new PersonalizeClient({ region: "REGION"});

// Set the filter's parameters.
export const createFilterParam = {
  datasetGroupArn: "DATASET_GROUP_ARN" /* required */,
  name: "NAME" /* required */,
  filterExpression: "FILTER_EXPRESSION" /*required */,
};

export const run = async () => {
  try {
    const response = await personalizeClient.send(
      new CreateFilterCommand(createFilterParam),
    );
    console.log("Success", response);
    return response; // For unit tests.
  } catch (err) {
    console.log("Error", err);
  }
};
run();
