Answer 1

Finally, I am able to find the solution for this. It can be done by setting headers to InitiateMultipartUploadRequest object as follow:

InitiateMultipartUploadRequest initRequest = new
                InitiateMultipartUploadRequest(bucketName, keyName);
        initRequest.putCustomRequestHeader("x-amz-server-side-encryption", "aws:kms");
        initRequest.putCustomRequestHeader("x-amz-server-side-encryption-aws-kms-key-id", kmsKey);

Answer 2

Can also be done like this:

InitiateMultipartUploadRequest initRequest = new InitiateMultipartUploadRequest("example-bucket", "textfile.txt");      SSEAwsKeyManagementParams kms = new SSEAwsKeyManagementParams("KMS-key-alias");
initRequest.setSSEAwsKeyManagementParams(kms);
initResponse = s3Client.initiateMultipartUpload(initRequest);
