How to generate a UPC-E barcode as a PNG file in Java

Today’s tutorial is going to showcase an unbelievably simple solution for UPC-E barcode generation for Java users. By taking this approach instead of trying to manually code your barcode creation, you will be saving yourself hours and probably a few gray hairs to boot. Let’s get right to it.

First we need the following repository reference for jipack.

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

Then comes our dependency.

<dependencies>
<dependency>
    <groupId>com.github.Cloudmersive</groupId>
    <artifactId>Cloudmersive.APIClient.Java</artifactId>
    <version>v3.54</version>
</dependency>
</dependencies>

And finally, we can call our function like this:

// 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 {

File result = apiInstance.generateBarcodeUPCE(value);

System.out.println(result);

} catch (ApiException e) {

System.err.println("Exception when calling GenerateBarcodeApi#generateBarcodeUPCE");

e.printStackTrace();

}

That’s it! Barcode generation is now yours to command.
