String connectionString = "";
String shareName = "";
String filePath = "<local file path>";
String fileName = "";

// Create a ShareClient object
ShareClient shareClient = new ShareClientBuilder().connectionString(connectionString).shareName(shareName).buildClient();

try {
    // Open the file as a stream
    File file = new File(filePath);
    FileInputStream fis = new FileInputStream(file);

    // Upload the file to the share
    ShareFileClient fileClient = shareClient.getDirectoryClient("").getFileClient(fileName);
    fileClient.create(fis.available());
    fileClient.upload(fis, fis.available());

    // Close the file stream
    fis.close();

    System.out.println("File uploaded successfully.");
} catch (IOException e) {
    e.printStackTrace();
}

are you using Azure SDK in your project? The error message looks like a dependent jar file is missing. — Raju Rudru, Aug 01 '23 at 09:05

Need to upload the file from local to Azure blob File Share folder using Java code

You can use the below code to upload from the local path to Azure file storage using Azure Java SDK.

Code:

import com.azure.storage.file.share.ShareFileClient;
import com.azure.storage.file.share.ShareFileClientBuilder; 

    public static void main(String[] args) {
        String connectionString = "your-connection-string";
        String shareName = "fileshare1";
        String directoryName = "directory1";
        String fileName = "sample.csv";
        String filePath = "C:\\Users\\xxxx\\xxxx\\day.csv";
    
        // Create a ShareClient object
               // Create a ShareFileClient object
        ShareFileClient fileClient = new ShareFileClientBuilder()
                .connectionString(connectionString)
                .shareName(shareName)
                .resourcePath(directoryName + "/" + fileName)
                .buildFileClient();
    fileClient.uploadFromFile(filePath);
    
    System.out.println("File uploaded successfully.");
    }

Dependency:

<dependency>
  <groupId>com.azure</groupId>
  <artifactId>azure-storage-file-share</artifactId>
  <version>12.14.0</version>
</dependency>

Output:
