/**
 * Func is a java interface equivalent to JavaScript's Function for argument of #then
 * 
 * You can write Func like a JavaScript function.
 * I want to show two ways of implementing Func class.
 * 
 * No.1)Write Func object in the normal way.
 * 
Func function = new Func() {
    public void run(Action action, Object data) throws Exception {
        System.out.println("Process");//write your logic
        action.resolve();
    }
};

 * 
 * No.2)Write Func object using lambda expression.
 * 
Func function = (action, data) -> {
    System.out.println("Process");//write your logic
    action.resolve();
};
