Code :
try {

S3Client s3 = S3Client.builder()
.region(region)
.build();
S3Waiter s3Waiter = s3.waiter();
CreateBucketRequest bucketRequest = CreateBucketRequest.builder()
.bucket("abc")
.build();
s3.createBucket(bucketRequest); //creating s3 bucket
System.out.println("bucket........abc");
HeadBucketRequest bucketRequestWait = HeadBucketRequest.builder()

// Wait until the bucket is created and print out the response
WaiterResponse<HeadBucketResponse> waiterResponse =

waiterResponse.matched().response().ifPresent(System.out::println);
System.out.println("abc" " is ready");
} catch (S3Exception e) {
System.err.println(e.awsErrorDetails().errorMessage());
System.exit(1);
