请帮忙合并下面两个方法到第三个里面去

如果closeThePopupAndSetColor()函数没有其它参数，代码如下

private void closeThePopupAndSetColor(){
closeThePopupAndSetColor();    
self.hide();

 boolean hasData =false;
if(closingModel!=null) //closingModel在函数外面设置，因为函数没有设置参数
hasData = !closingModel.isNew();
    EventBus.doFireEvent(new SensorimotorExamUpdatedEvent(hasData));
}

如果closeThePopupAndSetColor()函数有SensorimotorExam closingModel参数，代码如下

private void closeThePopupAndSetColor(SensorimotorExam closingModel){
closeThePopupAndSetColor();    
self.hide();
 boolean hasData =false;
if(closingModel!=null) //调用第一个函数时，设置closingModel=null
hasData = !closingModel.isNew();
    EventBus.doFireEvent(new SensorimotorExamUpdatedEvent(hasData));
}
