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.
