# Use `CreateSchema` with an AWS SDK
<a name="personalize_example_personalize_CreateSchema_section"></a>

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

------
#### [ 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 createSchema(PersonalizeClient personalizeClient, String schemaName, String filePath) {

        String schema = null;
        try {
            schema = new String(Files.readAllBytes(Paths.get(filePath)));
        } catch (IOException e) {
            System.out.println(e.getMessage());
        }

        try {
            CreateSchemaRequest createSchemaRequest = CreateSchemaRequest.builder()
                    .name(schemaName)
                    .schema(schema)
                    .build();

            String schemaArn = personalizeClient.createSchema(createSchemaRequest).schemaArn();

            System.out.println("Schema arn: " + schemaArn);

            return schemaArn;

        } catch (PersonalizeException e) {
            System.err.println(e.awsErrorDetails().errorMessage());
            System.exit(1);
        }
        return "";
    }
```
Create a schema with a domain.  

```
    public static String createDomainSchema(PersonalizeClient personalizeClient, String schemaName, String domain,
            String filePath) {

        String schema = null;
        try {
            schema = new String(Files.readAllBytes(Paths.get(filePath)));
        } catch (IOException e) {
            System.out.println(e.getMessage());
        }

        try {
            CreateSchemaRequest createSchemaRequest = CreateSchemaRequest.builder()
                    .name(schemaName)
                    .domain(domain)
                    .schema(schema)
                    .build();

            String schemaArn = personalizeClient.createSchema(createSchemaRequest).schemaArn();

            System.out.println("Schema arn: " + schemaArn);

            return schemaArn;

        } catch (PersonalizeException e) {
            System.err.println(e.awsErrorDetails().errorMessage());
            System.exit(1);
        }
        return "";
    }

**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). 

```
