Answer 1

Here's a simple Java Bean:
import java.io.Serializable;
public class SampleBean implements Serializable
    private static final String DEFAULT_MESSAGE = "Do a Google search on 'Java Beans next time'";
    private String message;
    public SampleBean() { this(DEFAULT_MESSAGE); }
    public SampleBean(final String message) { this.message = message; }
    public String getMessage() { return this.message; }
    public void setMessage(final String newMessage) { this.message = newMessage; }
}Do a Google search to learn more. Sun has Java Bean tutorials.
