Upload a File

The following tasks guide you through using the high-level Java classes to upload a file. The API provides several variations, called overloads, of the upload method to easily upload your data.

High-Level API File Uploading Process

1

Create an instance of the TransferManager class.

2

Execute one of the TransferManager.upload overloads depending on whether you are uploading data from a file, or a stream.

The following Java code example demonstrates the preceding tasks.

Example

The following Java code example uploads a file to an Amazon S3 bucket. For instructions on how to create and test a working sample, see Testing the Java Code Examples.
