Generate a barcode

Examplejava
import com.floms.openbarcode.linear.UPC;
int[] bars = new UPC("03600029145").barcode(); // 95 modules

The example encodes UPC-A 03600029145, which gets check digit 2 and produces 95 modules. The same input gives the same modules in every Open Barcode library.

More examples

Each example uses the same modules as the tests, so the output matches the other languages.

Three barcode typesjava
import com.floms.openbarcode.linear.*;

int[] upc = new UPC("03600029145").barcode();     // 95 modules
int[] ean = new EAN("400638133393").barcode();    // 95 modules
int[] code39 = new Code39("CODE39").barcode();    // 103 modules
Wrong check digitjava
import com.floms.openbarcode.linear.UPC;

try {
    new UPC("036000291453"); // the check digit should be 2
} catch (IllegalArgumentException e) {
    System.out.println(e.getMessage());
}
