Java quick start

Last updated: Feb-20-2024

This quick start lets you get an end-to-end implementation up and running using the Java SDK in 5 minutes or less.

1. Set up and configure the library

Using a clean Java project using Maven, add the cloudinary and dotenv dependencies to the list of dependencies in pom.xml:

pom.xml

Note
We recommend updating the version number to use the latest version of the Java SDK.

Then, in your project, create a file called .env and add the following line with your Cloudinary environment variable (replace cloudinary://<API_KEY>:<API_SECRET>@<CLOUD_NAME> below with your own environment variable value):

.env

Important
When writing your own applications, follow your organization's policy on storing secrets and don't expose your API secret.

In your code, include the following Cloudinary libraries as well as the dotenv library in your project. Copy and paste the following code into your Main.java file:

Main.java

You can now load your Cloudinary credentials from your .env file as shown below. Copy and paste the following code into your Main class:

Main.java (continued)

2. Upload an image

Copy and paste the following code into a try block within your Main class:

Main.java (continued)

3. Get details of the image

Main.java (continued)

4. Transform the uploaded image

Main.java (continued)

5. Run your code

Run your code by clicking the Run button on the main class.

You can use the returned image tag to display the image on your website. For now, copy and paste the URL to see the transformed image in the browser:

Transformed coffee_cup image

View the completed code

You can find the full code example for this on GitHub.
