Converting from Object to Button

I have code like this:
public void mouseClicked(java.awt.event.MouseEvent event)
{
      Object object = event.getSource();
      if (object == cmdPlay0 ||
            object == cmdPlay1 ||
            object == cmdPlay2 ||
            object == cmdPlay3 ||
            object == cmdPlay4 ||
            object == cmdPlay5 ||
            object == cmdPlay6 ||
            object == cmdPlay7 ||
            object == cmdPlay8)
            cmdPlay_MouseClicked(event, object);
}

Passing the object to cmdPlay_MouseClicked.  In the procedure cmdPlay_MouseClicked, I want to reference the specific button clicked.  Something like this:
void cmdPlay_MouseClicked(java.awt.event.MouseEvent event, Object objTarget)
{
      Button btnTarget = objTarget;
      if (btnTarget.getLabel() != "X") {
            btnTarget.setLabel("X");
      }
                  
}

The problem is that it doesn't want to convert objTarget to btnTarget.

How do I do this?
