### Generate Code 128 Barcode Image in Java

Source: https://github.com/woo-j/okapibarcode/blob/master/README.md

Use this snippet to generate a Code 128 barcode image in Java. It configures barcode properties and renders it to a PNG file using the Java 2D renderer.

```java
Code128 barcode = new Code128();
barcode.setFontName("Monospaced");
barcode.setFontSize(16);
barcode.setModuleWidth(2);
barcode.setBarHeight(50);
barcode.setHumanReadableLocation(HumanReadableLocation.BOTTOM);
barcode.setContent("123456789");

int width = barcode.getWidth();
int height = barcode.getHeight();

BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_BYTE_GRAY);
Graphics2D g2d = image.createGraphics();
Java2DRenderer renderer = new Java2DRenderer(g2d, 1, Color.WHITE, Color.BLACK);
renderer.render(barcode);

ImageIO.write(image, "png", new File("code128.png"));
```

### Generate Barcode SVG for Android in Java

Source: https://github.com/woo-j/okapibarcode/blob/master/README.md

This snippet demonstrates how to generate an SVG representation of a Code 128 barcode using Java. The SVG content can then be used with Android libraries for rendering.

```java
Code128 barcode = new Code128();
barcode.setFontName("Monospaced");
barcode.setFontSize(16);
barcode.setModuleWidth(2);
barcode.setBarHeight(50);
barcode.setHumanReadableLocation(HumanReadableLocation.BOTTOM);
barcode.setContent("123456789");

ByteArrayOutputStream stream = new ByteArrayOutputStream();
SvgRenderer renderer = new SvgRenderer(stream, 1, Color.WHITE, Color.BLACK, true);
renderer.render(barcode);

String content = new String(stream.toByteArray(), StandardCharsets.UTF_8);
SVG svg = SVG.getFromString(content);
svg.renderToCanvas(canvas);
```
