Java
1public void doesBucketExist (BosClient client, String bucketName) {
2 // Retrieve bucket existence information
3 // Specify the bucket name
4 boolean exists = client.doesBucketExist(bucketName);
5 // Output result
6 if (exists) {
7 System.out.println("Bucket exists");
8 } else {
9 System.out.println("Bucket not exists");
