Generate Code 39 Barcodes in Java

Generating Code 39 barcode in Java class example:

	Code39 barcode = new Code39();
	   Code 39 Valid data char set:
	        0, 1, 2, 3, 4, 5, 6, 7, 8, 9 (Digits)
	        A - Z (Uppercase letters)

	   Code 39 extension Valid data char set:
	        All ASCII 128 characters
	// Code 39 encodes upper case chars only, for lower case chars, use Code 39 extension
	// Code 39 Wide Narrow bar Ratio
	// Valid value is from 2.0 to 3.0 inclusive.
	// The space between 2 characters in code 39; This a multiple of X; The default is 1.;
	// Valid value is from 1.0 (inclusive) to 5.3 (exclusive)
	// Code 39 Unit of Measure, pixel, cm, or inch
	// Code 39 barcode bar module width (X) in pixel
	// Code 39 barcode bar module height (Y) in pixel
	// Code 39 image margins
	// barcode image resolution in dpi
	// disply barcode encoding data below the barcode
	// barcode encoding data font style
	barcode.setTextFont(new Font("Arial", 0, 12));
	// space between barcode and barcode encoding data
	//  barcode displaying angle
