Amazon web services – Error while generating AWS session token using java

I am trying to use session token using AWS sts_client

AWSSecurityTokenService sts_client =  AWSSecurityTokenServiceClientBuilder.standard()
                                             .withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration("https://sts.ap-southeast-2.amazonaws.com", "ap-southeast-2"))
                                             .withRegion(Regions.AP_SOUTHEAST_2).build();

getting below error.

java.lang.IllegalStateException: Only one of Region or EndpointConfiguration may be set.

    You have to use Amazon STS for temporary credentials. You get those credentials, including token, using for example AssumeRole.

    This below code working for me:

    AWSCredentials credentials = new BasicAWSCredentials("—-ACESSKEY—-",
    "—SECRET ACCESS KEY");

        AWSCredentialsProvider credentialsProvider = new AWSStaticCredentialsProvider(credentials);

    AssumeRoleRequest assumeRequest = new AssumeRoleRequest()
            .withRoleArn("--------RoleArn----------")
            .withDurationSeconds(3600).withRoleSessionName("TEST");

    AWSSecurityTokenService securityTokenService = AWSSecurityTokenServiceClientBuilder.standard()
            .withRegion(Regions.US_EAST_1).withCredentials(credentialsProvider).build();

    AssumeRoleResult result = securityTokenService.assumeRole(assumeRequest);
