Reading and Sorting Barcodes in Specific Order in Java

Introduction

In the dynamic world of Java programming, efficiently handling barcodes is a common requirement for many applications. Aspose.BarCode for Java emerges as a powerful tool, offering seamless integration for barcode reading and sorting. In this tutorial, we’ll explore how to read and sort barcodes in a specific order using Aspose.BarCode for Java.

Prerequisites

Before diving into the code, ensure you have the following prerequisites:

• Java Development Kit (JDK): Aspose.BarCode for Java requires a functioning JDK. You can download the latest version here.

• Aspose.BarCode Library: Make sure you have the Aspose.BarCode library. You can obtain it from the download link.

Import Packages

Begin by importing the necessary packages into your Java project. These packages provide the essential classes and methods for working with barcodes.

// Import Aspose.BarCode classes
import com.aspose.barcode.barcoderecognition.BarCodeReader;
import com.aspose.barcode.barcoderecognition.BarCodeResult;
import com.aspose.barcode.barcoderecognition.DecodeType;

import java.awt.Point;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;

Now, let’s break down the code into a step-by-step guide:

Step 1: Set up the Resource Directory

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

Replace "Your Document Directory" with the actual path to your document directory.

Step 2: Specify Barcode Image Path and Initialize Reader

String path = dataDir + "barcode.png";
List<FoundBarCodes> found = new ArrayList<FoundBarCodes>();

// Initialize BarCodeReader with the specified path and decode type
BarCodeReader reader = new BarCodeReader(path, DecodeType.CODE_128);

Step 3: Read Barcodes and Store Results

// Iterate through barcodes and store results
for (BarCodeResult result : reader.readBarCodes()) {
    found.add(new FoundBarCodes(result.getCodeText(), result.getRegion()));
}

Step 4: Define Comparator for Sorting

// Define a comparator for sorting barcodes based on code text
Comparator<FoundBarCodes> foundComparator = new Comparator<FoundBarCodes>() {
    @Override
    public int compare(FoundBarCodes e1, FoundBarCodes e2) {
        return e1.getCodeText().compareTo(e2.getCodeText());
    }
};

Step 5: Sort Barcodes

// Sort the list of barcodes using the defined comparator
found.sort(foundComparator);

Step 6: Display Sorted Barcodes

// Display sorted barcodes with their coordinates
int i = 1;
for (FoundBarCodes barcode : found) {
    Point[] point = barcode.BarCodeRegion.getPoints();
    System.out.println("Codetext ( " + i + " ): " + barcode.CodeText);
    System.out.println("Top left coordinates: X = " + point[0].getX() + ", Y = " + point[0].getY());
    System.out.println("Bottom left coordinates: X = " + point[1].getX() + ", Y = " + point[1].getY());
    System.out.println("Bottom right coordinates: X = " + point[2].getX() + ", Y = " + point[2].getY());
    System.out.println("Top right coordinates: X = " + point[3].getX() + ", Y = " + point[3].getY());
    System.out.println();
    i++;
}

Conclusion

In this tutorial, we’ve explored how to leverage Aspose.BarCode for Java to read and sort barcodes in a specific order. By following the step-by-step guide, you can enhance your Java applications with efficient barcode processing capabilities.
