java - 想要通过 ids 列表获取 ArrayList 中的元素

Question

我有一个ArrayList<UIToto> ，每个UIToto包含

(String id, String name, String info)

例如

(4546-fdsf4545sfd-dfs545, titi, female)
(dqs4d65q4-45d4s54545sfd-dfss54545, tutu, male)

我有一个 id 列表，例如

String ids = "dqs4d65q4-45d4s54545sfd-dfss54545, 4545-dsqd45-dqs,4d5s44-ss4-dqsd";

对于每个 id，我检索 id，并希望在我的 ArrayList 中获取 UIToto:

ArrayList<UIToto> totoList = retrieveTotoList();
String[] ids = "dqs4d65q4-45d4s54545sfd-dfss54545, 4545-dsqd45-dqs,4d5s44-ss4-dqsd";
for(int i=0; i <= ids.length; i++) {
    System.out.println(("id = " + ids[i]);
    //don't work because it's not the index but the id ...
UIToto response = totoList.get(Integer.parseInt(ids[1]));
System.out.println("response = " + response);
 }

可能吗？

谢谢!

尝试

ArrayList<UIToto> totoList = retrieveTotoList;
ArrayList<UIToto> resultList= new ArrayList<UIToto>();

String[] ids = {"dqs4d65q4-45d4s54545sfd-dfss54545", 
                "4545-dsqd45-dqs,4d5s44-ss4-dqsd"}; 

for(int i = 0; i < ids.length; i++) {
    for(UIToto uIToto : totoList) {
        if(uIToto.getId().equals(ids[i])) {
            resultList.add(uIToto);     
        }
    }
}
