Java Code 39 Barcode Generator Introduction

KA.Barcode for Java is an advanced barcode generator which is very professional in creating great quality Code 39 barcodes and many other 1D and 2D barcode symbologies in Java class. Users can adjust the parameters of the barcodes easily.

Code 39 Barcode Overview in Java

Code 39 is a discrete and self-checking symbology which has variable data length. It is also called Alpha39, Code 3 of 9, Type 39, USS Code 39 and USD-3. This barcode is widely adopted in non-retail fields.

Code 39 Encodable Character Set

Alphanumeric data: 0-9, A-Z
Special characters: space $ % + - . /
Start/stop character *

Code 39 Introduction

Code 39, also named as 3 of 9 Code, USD-3, Alpha39, Code 3/9, Type 39 & USS Code39, is a self-checking linear barcode symbology which encodes alphanumeric data, including alphanumeric data: 0-9, A-Z; special characters: space $ % + - . / and start/sop character: *.

Using Java Barcode Generator library, you can not only generate Code 39 barcodes in the Java class, but also generate Code 128, encode GS1-128, generate QR Code, create Data Matrix, generate PDF-417, generate EAN-13, and create UPC-A barcodes in your Java web applications.

Code 39 Character Set Encoding in Java

Code 39 standard mode in Java

Code 39 barcode standard mode supports 43 characters, including

Numeric digit: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
Uppercase letters (A - Z)
Special characters: - (Dash), $ (Dollar), % (Percentage), (Space), . (Point), / (Slash), + (Plus)
Start/Stop character

To generate Code 39 with standard mode characters in Java class, you need choose "setSymbology()" as IBarCode.CODE39 in Java code.

Code 39 full ASCII mode in Java

Code 39 supports encoding the full 128 character ASCII character set in accordance with ISO 646 IRV.

To generate Code 39 with 128 ASCII characters in java class, you need choose "setSymbology()" as IBarCode.CODE39Ex in Java code.

Code 39 start/stop characters in Java

Code 39 uses asterisk character (*) as Start and Stop characters, and it should not be part of the Code 39 barcode data.

In the Code 39 displayed text area (Human-readable interpretation), it can display or hide start/stop characters (asterisk *).

Using Java Code 39 generator, you can easily customize to show or hide the start/stop characters in displayed code 39 text. Call method setDisplayStartStop(true or false).

Code 39 symbol check digit in Java

Code 39 does not include a checksum or check digit by default. For applications requiring enhanced data security, the modulo 43 (MOD43) check character may be used as a check digit.

To enable Code 39 check digit in your Java program, you need apply the method setChecksumEnabled() to turn on or off applying check sum digit in Java class.

Generate Code 39 in Java Class with Sample Code

A sample code for generating a Code 39 barcode in Java class is presented below. The properties of Code 39 are adjustable. So you can create the barcodes you want by changing the properties.

Sample code

     public static void main(String[] args)
     {

     BarCode code39 = new BarCode();

     code39.setCodeToEncode("123456789");
     code39.setSymbology(IBarCode.CODE39);
     code39.setX(2);
     code39.setY(50);
     code39.setRightMargin(0);
     code39.setLeftMargin(0);
     code39.setTopMargin(0);
     code39.setBottomMargin(0);
     code39.setChecksumEnabled(false);
     code39.setDisplayStartStop(true);
     code39.setWideNarrowRatio(2.0f);
      
     try
     {

     code39.draw("c://code39.gif");

     }
     catch (Exception e) {
     e.printStackTrace();
     }
     }
     }
