To use Stook with Java, follow the steps below:

• Click the link for AWS Java SDK.

• SDK has many code examples to help you begin easily.

• This sample code is given below to create a bucket and upload an object.

               .withCannedAcl(CannedAccessControlList.PublicRead);
           AMAZON_S3_CLIENT.putObject(putObjectRequest);

           return AMAZON_S3_CLIENT.getUrl(BUCKET_NAME, filename).toString();
       }
   }

   public static void main(String[] args) {


       if (!AMAZON_S3_CLIENT.doesBucketExistV2(BUCKET_NAME)) {
           // Because the CreateBucketRequest object doesn't specify a region, the
           // bucket is created in the region specified in the client.
           AMAZON_S3_CLIENT.createBucket(new CreateBucketRequest(BUCKET_NAME));

           // Verify that the bucket was created by retrieving it and checking its location.
           String bucketLocation = AMAZON_S3_CLIENT.getBucketLocation(new GetBucketLocationRequest(BUCKET_NAME));
           System.out.println("Bucket location: " + bucketLocation);
       }

           try {
                uploadFile("Hello World".getBytes());
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
       System.out.println("Hello, World");
   }
