Java Barcode Generator is a mature Java Barcode Library SDK (jar files) which enables developers to easily generate over 30 linear & 2D (two-dimensional) barcode types in Java programs, including major GS1, ISO/IEC, postal barcodes. With this Java barcode jar, users can stream barcodes in Java Server Side projects like JSP, Java Servlet, apart from Java Class, Jasper Report, and Eclipse BIRT, Oracle Report. Besides, the intuitive interface provides full features & flexible functions for barcode control & design.

How to Encode GS1 Barcodes in Java Class
Top
This Java Barcode Library can encode UPC/EAN Barcodes with GS1 standard pre-configured. Alternatively, if you want to encode GS1-compatible QR Code, Data Matrix, GS1-Databar, GS1-128/EAN-128 or ITF-14, please follow the basic Java class sample code here.
Please note that the checksum character is automatically calculated and added to some linear barcode with obligatory check digit requirement. If you want to reduce barcode size, change barcode value, customize image color / orientation, or switch to another output method, simple add more in the Java barcode syntax below.
To learn how to adjust barcode image formats into GIf / Jpeg (Jpg)/ Png / Tiff, please navigate to Java Barcode Image Setting Tutorial

Create GS1-DataBar Barcode in Java Class


GS1DataBar gs1databar = new GS1DataBar();
//Set GS1-Databar barcode data string - encoding example numbers
gs1databar.setData("11111555551234");

//Adjust barcode size of GS1-Databar
gs1databar.setX(2);
gs1databar.setY(60);
gs1databar.setBarcodeWidth(220);

//Set GS1 DataBar image rotation and display text
gs1databar.setRotate(0);
gs1databar.setShowText(true);

gs1databar.drawBarcode("C://ob-gs1databar.gif");

Create GS1-128/EAN-128 Barcode in Java Class


EAN128 gs1128 = new EAN128();
gs1128.setData("(12)445566");

//Control GS1-128 barcode size with Java coding
gs1128.setUom(0);
gs1128.setX(2);
gs1128.setY(60);
gs1128.setLeftMargin(10);
gs1128.setRightMargin(10);

//Set GS1-128 image orientation and image format into Gif
gs1128.setRotate(0);
gs1128.setImageFormat(1);

gs1128.drawBarcode("C://ob-gs1128.gif");

Create GS1 ITF-14 Barcodes in Java Class


ITF14 itf14 = new ITF14();
itf14.setData("00000555551234");

//Resize ITF-14 barcode image size with Java code
itf14.setUom(0);
itf14.setX(2);
itf14.setY(60);
itf14.setN(2);

//Set ITF-14 bearer bar style as required by GS1 standard
itf14.setBearerBarHori(2);
itf14.setBearerBarVert(2);

itf14.setImageFormat(3);
itf14.drawBarcode("C://ob-itf14.png");

Create GS1-Compatible QR Code in Java Class


QRCode qrcode = new QRCode();
//Select QR Code Data Mode and encoding data
qrcode.setDataMode(0);
qrcode.setData("(01)55678");

//Set QR Code FN1 to enable GS1-compatibility
qrcode.setFnc1Mode(1);

//Adjust QR Code barcode size through module and quiet zone
qrcode.setX(2);
qrcode.setLeftMargin(8);
qrcode.setRightMargin(8);
qrcode.setTopMargin(8);
qrcode.setBottomMargin(8);

//Set barcode image format, resolution and then generate it
qrcode.setImageFormat(1);
qrcode.setResolution(96);
qrcode.drawBarcode("C://java-qrcode.gif");

Create GS1-Compatible Data Matrix in Java Class


DataMatrix datamatrix = new DataMatrix();
datamatrix.setDataMode(0);
datamatrix.setData("456789");

//Select FNC1 Mode to encode GS1-compatible Data Matrix
datamatrix.setFnc1Mode(1);

//Resize Data Matrix barcode image
datamatrix.setFormatMode(4);
datamatrix.setX(3);
datamatrix.setTopMargin(3);
datamatrix.setBottomMargin(3);
datamatrix.setLeftMargin(3);
datamatrix.setRightMargin(3);

datamatrix.drawBarcode("C://java-datamatrix.gif");
How to Encode Unicode into Barcodes in Java Class
Top
The ISO/IEC 8859-1 standard character set is used in various barcode types, as it covers a wide range of characters in English, French, Italian, Spanish, etc. However, if you want to encode data from other character sets, such as Arabic, Chinese, Japenese and Greek, you can simply convert the special char to Unicode encoding first, and then encode it in QR Code, Data Matrix or PDF-417.
Below is the Java demo code for 2D barcodes generation & encryption, in which UTF-8 encoding is applied to convert the original data to Unicode. Please note that the decoded data need to be converted back so you can get your original data for the barcode image.
