AmazonS3ClientBuilder ; import com. Non-alphanumeric characters are percent encoded. This encoding type is not suitable for binary files. The input element's type attribute is set to file.

In the following application, we have a web form to select a file to be uploaded to the server. The form calls a Java servlet, which reads the file and saves it into the directory. Set the region closest to where your users will be. Then, we've created an S3Client object and used its builder , passing the region, to instantiate it.

Finally, to create a bucket, we'll need to pack everything in a request and fire that request using the S3Client instance. To pack everything in a request, we call the builder of the CreateBucketRequest class and pass the bucket's name and region ID.

Note : Amazon bucket names must be unique globally. Change the new-bucket name with another one. We've populated it with a random byte buffer. When we run this code, a new file named key will be uploaded to the bucket. In addition to the previous classes, and in the same fashion, the DeleteBucketRequest class is used to send a request for the deletion of a bucket.
