How to open blobs on browser without downloading through java service?

I am creating an application where I need to view blobs in browser rather than downloading them. Currently, links of blobs having token downloads the corresponding blob.

I got some reference here to view the blobs in browser : https://github.com/Azure-Samples/storage-blob-java-getting-started/blob/master/src/BlobBasics.java (See from line number 141)

Here is my code to create token :

@Test
    public String testBlobSaS(CloudBlob blob, CloudBlobContainer container) throws InvalidKeyException,
            IllegalArgumentException, StorageException, URISyntaxException, InterruptedException {
        SharedAccessBlobPolicy sp = createSharedAccessBlobPolicy(
                EnumSet.of(SharedAccessBlobPermissions.READ, SharedAccessBlobPermissions.LIST), 100);
        BlobContainerPermissions perms = new BlobContainerPermissions();
        perms.getSharedAccessPolicies().put("readperm", sp);
        perms.setPublicAccess(BlobContainerPublicAccessType.CONTAINER);
        container.uploadPermissions(perms);
        String sas = blob.generateSharedAccessSignature(sp, null);
        CloudBlockBlob sasBlob = new CloudBlockBlob(
                new URI(blob.getUri().toString() + "?" + blob.generateSharedAccessSignature(null, "readperm")));
        sasBlob.download(new ByteArrayOutputStream());
        CloudBlob blobFromUri = new CloudBlockBlob(
                PathUtility.addToQuery(blob.getStorageUri(), blob.generateSharedAccessSignature(null, "readperm")));
        assertEquals(StorageCredentialsSharedAccessSignature.class.toString(),
                blobFromUri.getServiceClient().getCredentials().getClass().toString());
        StorageCredentials creds = new StorageCredentialsSharedAccessSignature(
                blob.generateSharedAccessSignature(null, "readperm"));
        CloudBlobClient bClient = new CloudBlobClient(sasBlob.getServiceClient().getStorageUri(), creds);
        CloudBlockBlob blobFromClient = bClient.getContainerReference(blob.getContainer().getName())
                .getBlockBlobReference(blob.getName());
        assertEquals(StorageCredentialsSharedAccessSignature.class.toString(),
                blobFromClient.getServiceClient().getCredentials().getClass().toString());
        assertEquals(bClient, blobFromClient.getServiceClient());
        return sas;
    } 

I have added this line into code from reference of url provided earlier:

perms.setPublicAccess(BlobContainerPublicAccessType.CONTAINER);

I have code which gives me url for blob with token like :

https://accountName.blob.core.windows.net/directories/blobName?token

Still with this url, it's downloading the respective blob. What changes I should make in code while creating token, so that I can view blobs in browser itself without downloading?
