Java: Reset Singleton Object

Question

I have created a dashboard that is Singleton. But I want to refresh(reload the default values) it every time a button is clicked. What could be best possible way to achieve this?

Code for the class:

public class UserDashboard extends Composite{ private static UserDashboard userDash= new UserDashboard(); private UserDashboard(){ initWidget(uiBinder.createAndBindUi(this)); } public static UserDashboard getDashInstance(){ return userDash; }}

What do you mean by refresh?

Just add a method which refreshes the singleton instance without recreating it.
You can put any meaning into refreshes (whatever appropriate).

then i need to explicitly set all the values to the default? there are lot many classes running on top of this class. Can't go on setting their values to default.

@Forkmohit "then i need to explicitly set all the values to the default" >>> What do you suggest instead?
