Generate Barcodes in Java Console Application

Developers might need to generate barcode images at the back end programmatically. This requirement can be useful to:

• generate barcode images and then save them to a database
• save barcode images in some other locations after creating them at runtime
• integrate the barcode generation feature into some other applications

There can be many other reasons to work with barcodes at the back end which depend upon the developer’s requirements.

Aspose.BarCode provides class BarcodeGenerator to generate barcodes. Developers can create an instance of this class, set properties, and save the barcode image to any location.

The resulting barcode image generated by the code above can be seen below.

Generate Barcodes in Java Swing application

Follow the steps below to use Aspose.BarCode in Java Swing applications:

1. Design your Swing application as shown in the figure below using your choice of the GUI tool. For example, Netbeans, or Eclipse

2. Activate the license to the control to avoid the evaluation watermark in the barcode image. The code that enables the license can be added to the constructor or some custom initialization method of the form

3. Add the code to the project:

4. On the button event handler method, write the following code to generate the barcode image and save it to disk. Then, use the Graphics object to render the image on the frame

5. Run the application. You should get output similar to the screenshot below
