title: Can I update an existing Amazon S3 object?
body: <p>I was looking at Amazon S3 Samples, and the samples are there for inserts/deletes...</p>
  
  <p>But I want to update an existing blob with fresh data. Basically the content is a text file, and the text has been modified, I want the S3 object to store the new text content.</p>
  
  <p>How do I do this in Java? </p>
