Answer 1

Use a list of buttons (or even an array of buttons) :

List<JButton> listOfButtons = new ArrayList<JButton>(collection.size());
for (int i=0; i < collection.size(); i++) {
    JButton button = new JButton();
    listOfButtons.add(button);
}

Answer 2

创建一个List<JButton> ，每次通过你的循环add新的JButton 。
