Building a basic JavaBean
Basic Bean Info
Up to this point in the course you've learned a lot about the composition of Beans and how Beans are organized. This module closes on a practical note by allowing you to build a basic
Bean based on a lot of the things you've learned thus far. In this lesson, you build a Bean that displays a text label.
The basic Bean you build in this lesson, MyLabel, contains a single property called label that is displayed as the Bean's only graphical output.
This Bean can be used as an output control to display text. The MyLabel
Bean consists of the following major
- A label property
- Constructors for the Bean
- Accessor methods for the label property
- A paint() method to draw the label text
