The Amazon S3 API does not have an API method for this. You can use Java logic to obtain the bucket name and object name from an Object ARN. Here is your solution.

    String arn = "arn:aws:s3:::bucketmay10002/book.pdf";
    String bucketObject = "";


    String[] value1 = arn.split(":::");
    for (String t : value1){
        bucketObject = t ;
        System.out.println(bucketObject);
}

    String[] value3 = bucketObject.split("/");
    for (String t : value3)
        System.out.println(t);
}

Output:

  • arn:aws:s3
  • bucketmay10002/book.pdf
  • bucketmay10002
  • book.pdf

As you can see, you get both the bucket name and object name from the given object ARN.
