public class SimpleBean {

    // Getter for the "State" property.
    public String getState() {
        return state ;
    }
  
    // Setter for the "State" property.
    public void setState(String s) {
        state = s ;
        nbChanges++ ;
    }
  
    // Getter for the "NbChanges" property.
    public Integer getNbChanges() {
        return new Integer(nbChanges) ;
    }
  
    // Action on the "NbChanges" property.
    public void performReset() {
        nbChanges = 0 ;
    }

    // M-bean properties.
    protected String state = "initial state" ;
    protected int nbChanges = 0 ;
}

To compile the m-bean, type this command: 
prompt% javac SimpleBean.java
