Generating fields from a bean

In some situations, we need to create a form very quickly. For example, when we are creating a proof of concept, a prototype of an application, or when we need only a simple form and we don't want to spend a lot of time on UI work. In those cases, we don't need to create each field, but we can generate them through the Java Bean. It's quick and easy. In this recipe, we will see how to generate a simple form for the Bean Product. Our generated form will look like the following screenshot:

How to do it...

Carry out the following steps to generate a form from the Java Bean:

1. Create a Vaadin project with a main UI class called Demo.

   public class Demo extends UI {…}

2. We start with a bean. This bean is for Product that has attributes code, name, price, and date. Names of the getter methods (without the prefix 'get' and 'is') will be used as captions for the generated fields.

   public class Product {
   
     private int code;
     private String name;
     private double price;
