Generate a UPC-E Barcode as a PNG File using Java

If you’re selling products with small packaging, you’ll need a smaller barcode than the standard UPC-A variation.

That’s why UPC-E barcodes exist — and you can easily generate them as PNG files using our UPC-E generation API. Take advantage of ready-to-run code provided below from our API console page (in java) to implement easily into your environment.

To start, install the Java SDK with Maven (instructions for Gradle are available on our API Console page). Add a reference to the pom.xml repository:

<repositories>
    <repository>
        <id>jitpack.io</id>
        <url>https://jitpack.io</url>
    </repository>
</repositories>

Then add a reference to the pom.xml dependency:

<dependencies>
<dependency>
    <groupId>com.github.Cloudmersive</groupId>
    <artifactId>Cloudmersive.APIClient.Java</artifactId>
    <version>v4.25</version>
</dependency>
</dependencies>

All that’s left now is to add in the import classes, copy in the barcode-generating function and supply your Cloudmersive API key where indicated:

// Import classes:
//import com.cloudmersive.client.invoker.ApiClient;
//import com.cloudmersive.client.invoker.ApiException;
//import com.cloudmersive.client.invoker.Configuration;
//import com.cloudmersive.client.invoker.auth.*;
//import com.cloudmersive.client.GenerateBarcodeApi;
ApiClient defaultClient = Configuration.getDefaultApiClient();
// Configure API key authorization: Apikey
ApiKeyAuth Apikey = (ApiKeyAuth) defaultClient.getAuthentication("Apikey");
Apikey.setApiKey("YOUR API KEY");
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//Apikey.setApiKeyPrefix("Token");
GenerateBarcodeApi apiInstance = new GenerateBarcodeApi();
String value = "value_example"; // String | UPC-E barcode value to generate from
try {
    byte[] result = apiInstance.generateBarcodeUPCE(value);
    System.out.println(result);
} catch (ApiException e) {
    System.err.println("Exception when calling GenerateBarcodeApi#generateBarcodeUPCE");
    e.printStackTrace();
}
