Applying Checksum for CodaBar in Java

Introduction

Welcome to this step-by-step tutorial on applying checksum for CodaBar in Java using Aspose.BarCode. Aspose.BarCode for Java is a powerful library that allows developers to generate and recognize barcodes in Java applications seamlessly. In this tutorial, we will focus on the specific task of applying checksum for CodaBar barcodes.

Prerequisites

Before we dive into the tutorial, make sure you have the following prerequisites:

  • Java Development Kit (JDK) installed on your machine.
  • Aspose.BarCode for Java library. You can download it from here.
  • A basic understanding of Java programming.

Import Packages

In your Java project, make sure to import the necessary packages to work with Aspose.BarCode:

import java.io.IOException;

import com.aspose.barcode.CodabarChecksumMode;
import com.aspose.barcode.EnableChecksum;
import com.aspose.barcode.barcoderecognition.BarCodeReader;
import com.aspose.barcode.barcoderecognition.BarCodeResult;
import com.aspose.barcode.barcoderecognition.ChecksumValidation;
import com.aspose.barcode.barcoderecognition.DecodeType;
import com.aspose.barcode.generation.BarcodeGenerator;

Step 1: Set Up the Environment

Start by creating a new Java project and including the Aspose.BarCode library in your project’s dependencies. Set up your development environment with the required resources.

// The path to the resource directory.
String dataDir = "Your Document Directory";

Step 2: Generation of CodaBar Barcode

Now, let’s generate a CodaBar barcode with checksum enabled.

// Instantiate BarcodeGenerator object
BarcodeGenerator generator = new BarcodeGenerator(com.aspose.barcode.EncodeTypes.CODABAR, "1234567890");

// Set the EnableChecksum property to yes
generator.getParameters().getBarcode().setChecksumEnabled(EnableChecksum.YES);

// Set the CodabarChecksumMode
generator.getParameters().getBarcode().getCodabar().setCodabarChecksumMode(CodabarChecksumMode.MOD_10);

// Save the image on the system
generator.save(dataDir + "Codabar_Mod10.png");

Step 3: Recognition of CodaBar Barcode

Now, let’s implement the recognition part of the CodaBar barcode with checksum.

// Initialize reader object
BarCodeReader reader = new BarCodeReader(dataDir + "Codabar_Mod10.png", DecodeType.CODABAR);

// Set ChecksumValidation property of the reader to On
reader.setChecksumValidation(ChecksumValidation.ON);

for (BarCodeResult result : reader.readBarCodes()) {
    System.out.println("CodeText: " + result.getCodeText());
    System.out.println("Symbology type: " + result.getCodeType());

    // Get checksum value
    System.out.println("Checksum:" + result.getExtended().getOneD().getCheckSum());
}

Follow these steps to apply checksum for CodaBar in Java effortlessly using Aspose.BarCode.
