Creating a barcode in java

Nice little library to do this is located at http://www.barcodelib.com/java_barcode/main.html…

import com.barcodelib.barcode.*;

public class MyBarCode {
  public static void main (String args[]) throws Exception {
    Linear barcode = new Linear();
    barcode.setType(Linear.UPCA);
    java.util.Random r = new java.util.Random();
    String str = new Integer(Math.abs(r.nextInt())).toString();
    StringBuilder sb = new StringBuilder();
    for (int toPrepend=11-str.length(); toPrepend>0; toPrepend--) {
      sb.append('0');
    }
    sb.append(str);
    String s = sb.toString();
    System.out.println(s);
    barcode.setData(s);
    barcode.renderBarcode("c://barcode.gif");
  }
}
