谁能告诉我List<Operator>怎么遍历

Question

是这样的，我想把List<Operator> list放入Combo中去
（int i=0;i<list.size();i++){
    combo.setItems(list.get(i))
    
}我是这么做的，结果报错说setItems不适用list.get(i)，那应该怎么做呢，Operator是个类里面有3个基本变量
private int order;    private String key;    private String value;求帮助，我想了很久，基础太差想不出来，指点下吧

Answer 2

setItems 需要的参数和你传入的不匹配

Answer 3

你的combo应该是java swing你的组件吧，你看看则个setItems的方法的参数类型是什么，然后在创建这种类型的对象把她对应的属性值设置成你当前的Operator的对应的值就可以了

Answer 4

虽然说授人与鱼不如授人与渔，但我还是希望各位能给我个标准的准换答案，就是将List<Operator> ipList = new ArrayList<Operator>();
怎样才能放到combo里，太模糊的答案我刚才请教过没能理解才上网求助的

Answer 5

首先声明  本人新手 
如有错误  概不负责
combo是哪个类的实例？

Answer 6

combo下拉列表 他只接受String[]类型的

Answer 7

帮你顶，等高手来回答吧！我还是没有弄清楚 combo 是怎么定义的，是什么类型（JComboBox）？
