UPC-A, also known as Universal Product Code version A , UPC Code, UPC Symbol, GTIN-12, GS1-12, UCC-12, is the most common and well-known barcode symbology in the United States.S

Generate and create UPC-A barcode using Java is one of the functions in OnBarcode's Barcode for Java Generating Java library (jar file), which supports generating & printing UPC-A and 20+ other linear & 2D bar codes in Java application and software.

UPC-A Generator and Reader library, SDK & application
UPC-A Generator components and software include .NET UPC-A, C# UPC-A, VB.NET UPC-A, ASP.NET UPC-A, UPC-A Generator.

This document is providing a detailed Java sample source code about generating UPC-A barcodes in Java class using Java Barcode generation component. Complete UPC-A custmoization settings is included in Java UPC-A generating guide.

Generating UPC-A barcode in Java class example:

	UPCA barcode = new UPCA();
	
	/*
	   UPC-A Valid data char set:
	        0, 1, 2, 3, 4, 5, 6, 7, 8, 9 (Digits)
	
	   UPC-A Valid data length: 11 digits only, excluding the last checksum digit
	*/
	barcode.setData("01234567890");
	
	// for UPC-A with supplement data (2 or 5 digits)
	/*
	barcode.setSupData("12");
	// supplement bar height vs bar height ratio
	barcode.setSupHeight(0.8f);
	// space between barcode and supplement barcode (in pixel)
	barcode.setSupSpace(15);
	*/
	
	// UPC-A Unit of Measure, pixel, cm, or inch
	barcode.setUom(IBarcode.UOM_PIXEL);
	// UPC-A barcode bar module width (X) in pixel
	barcode.setX(3f);
	// UPC-A barcode bar module height (Y) in pixel
	barcode.setY(75f);
	
	// barcode image margins
	barcode.setLeftMargin(0f);
	barcode.setRightMargin(0f);
	barcode.setTopMargin(0f);
	barcode.setBottomMargin(0f);
	
	// barcode image resolution in dpi
	barcode.setResolution(72);
	
	// disply barcode encoding data below the barcode
	barcode.setShowText(true);
	// barcode encoding data font style
	barcode.setTextFont(new Font("Arial", 0, 12));
	// space between barcode and barcode encoding data
	barcode.setTextMargin(6);
	
	//  barcode displaying angle
	barcode.setRotate(IBarcode.ROTATE_0);
	
	barcode.drawBarcode("C:\\upca.gif");
