s3client.setObjectAcl("bucketName[/subDirectory]", fileName, CannedAccessControlList.PublicRead);
URL url = s3client.getUrl("bucketName[/subDirectory]", fileName);
String sharableLink = url.toExternalForm();

An alternative approach which allows for more finegrained control of who exactly is allowed to view the object (all users or authenticated users only):

    PutObjectRequest putObjectRequest = new PutObjectRequest(bucketName, keyName, image);
    AccessControlList acl = new AccessControlList();
    acl.grantPermission(GroupGrantee.AllUsers, Permission.Read); //all users or authenticated
    putObjectRequest.setAccessControlList(acl);
    s3client.putObject(putObjectRequest);

Found the answer in an amazon aws forum.

return s3Client.putObject(
   new PutObjectRequest(bucketName, objectKey, inputStream, metadata)
      .withCannedAcl(CannedAccessControlList.PublicRead));

The answer being

.withCannedAcl(CannedAccessControlList.PublicRead)
