Here I use the Azure Blob storage v12, you could refer to the below code. Further more information about this SDK you could check this source code:Azure Storage Blob client library for Java.

        String connectStr = "storage account connection";

        // Create a BlobServiceClient object which will be used to create a container client
        BlobServiceClient blobServiceClient = new BlobServiceClientBuilder().connectionString(connectStr).buildClient();

        BlobContainerClient containerClient = blobServiceClient.getBlobContainerClient("container name");

        BlobClient blobClient=containerClient.getBlobClient("blob name");

        System.out.println(blobClient.getBlobUrl());

You can try

 String blobKey = <key to your blob> 
 // Create a blob service client
 CloudBlobClient blobClient = account.createCloudBlobClient();

 CloudBlobContainer container = blobClient.getContainerReference(name);

 // get reference to the Blob you want to generate the SAS for:
 CloudBlockBlob blob = container.getBlockBlobReference(blobKey);

and call

blob.getUri();
