        Graphics2D g2d = (Graphics2D)g;
    
        Color startColor = Color.red;
        Color endColor = Color.blue;
    
        // A non-cyclic gradient
        GradientPaint gradient = new GradientPaint(startX, startY, startColor, endX, endY, endColor);
        g2d.setPaint(gradient);
        // Draw shapes...; see e586 Drawing Simple Shapes
    
        // A cyclic gradient
