How to loop through Vaadin buttons?

I wanted to know is it possible to loop through all buttons in multiple files? For example, let's say i have a few classes:
Class1.java 

Button btn1 = New Button("BUTTON");  
Button btn2 = New Button("BUTTON");

Class2.java 

Button btn3 = New Button("BUTTON");

I guess one way how to change each button's style would be like this: 

btn1.addStyleName("button");
btn2.addStyleName("button");
btn3.addStyleName("button");

But i want to change specific button colors without using addStyleName. The reason is - i have a lot of buttons that have the same caption. Any ideas?

Create your own button class:

class MyButton extends Button {

    public MyButton() {
        super();
        setCaption("BUTTON");
        addStyleName("button");
    }
}

I think your need is a kind of Util class which will return the button objects with same class name. And call this Util method wherever you need.

eg.

public static Button createButton{
    Button button = new Button();
    button.addStyleName("button");
    return button;
}
