If this is java Factory then we must use Java Factory:

Food demo = null; try{ order=order.substring(0, 1).toUpperCase() + order.substring(1); Class clazz = Class.forName(order); demo = (Food) clazz.newInstance(); }catch(Exception e){

}

return demo;

Working off @m_hr1 and over engineering for fun...

    try{
        return (Food)FoodFactory.class.getClassLoader().loadClass(camelCase(order)).newInstance();
    } catch ( Exception e ) {
        return null;
    }
}
private String camelCase(String name){
    return name.substring(0, 1).toUpperCase() + name.substring(1).toLowerCase();

I opted this way, to avoid a hard coded solution:

            if (Pizza.class.getName().equalsIgnoreCase(order)){
                return new Pizza();
            }
            if (Cake.class.getName().equalsIgnoreCase(order)){
                return new Cake();
            }
            return null;
