所以我正在编写一个程序，我必须将语言改为另一种语言，我已完成该部分，但我似乎无法让JComboBox更改语言，例如，如果用户单击日语中的语言JComboBox从英语变为Eigo，法语变为Furansugo是否有一段代码可以专门执行此操作并将其与ActionPerformed一起用于语言？
你可能不需要它，但这是我的代码：

我会尝试这个例子正确定义你的听众肯定会有所帮助。 我也不明白为什么你有3个捆绑实例...你应该根据所需的语言有1个..
Button button1 = new Button();
button1.setCaption(ResourceBundle.getBundle("yourfile",your_locale).getLabel("fruit.banana"));
button1.setIcon(CommonIcons.ADD);
button1.addListener(new ClickListener()
{
private static final long serialVersionUID = 7855693595481663167L;
@Override
public void buttonClick(ClickEvent event)
{
handleAddButton();
}
});
我认为你应该对此好。我还建议你创建一个jpgs数组和一个JButton数组...并在循环中初始化它们。这样你就可以管理n个对象，而不是复制凌乱的代码......
