有没有办法在java中将 String[] 转换为 List<AyrayList<>> ？

Question

我需要转换这个字符串数组String[] myStringArray0 = {"FTMORGANIZATION_NAME","FTMOBJECTNUMBER","FTMCONTAINERTYPE","FTMCONTAINER"};进入List<ArrayList<String>>其中所有的 "FTMOGNIZATION_NAME","FTMOBJECTNUMBER","FTMCONTAINERTYPE","FTMCONTAINER" 进入 ArrayList 并进入 List 对象。任何人都可以有建议吗？

Answer 1

String[] myStringArray0 = {"FTMORGANIZATION_NAME","FTMOBJECTNUMBER","FTMCONTAINERTYPE","FTMCONTAINER"};

List<List<String>> result = new ArrayList<>();

result.add(Arrays.asList(myStringArray0));

Answer 2

使用该Arrays.asList方法创建一个ArrayList，然后简单地将其添加到一个List

String[] myStringArray0 = {"FTMORGANIZATION_NAME","FTMOBJECTNUMBER","FTMCONTAINERTYPE","FTMCONTAINER"};

ArrayList<String> arraylist = new ArrayList<>(Arrays.asList(myStringArray0));

List<ArrayList<String>> list = new ArrayList();

list.add(arraylist);

Answer 3

你可以试试我下面贴的，希望对你有帮助

String[] myStringArray = {"FTMORGANIZATION_NAME", "FTMOBJECTNUMBER", "FTMCONTAINERTYPE", "FTMCONTAINER"};

        List<String> list = new ArrayList<String>();

        list.add(Arrays.toString(myStringArray));

        System.out.println("list : " + list.toString());

list : [[FTMORGANIZATION_NAME, FTMOBJECTNUMBER, FTMCONTAINERTYPE, FTMCONTAINER]]

Answer 4

您可以定义一个for循环并将字符串数组的每个元素添加到 ArrayList。

前任 ：ArrayList<String> values = new ArrayList<>();

for(int i=0; i<myStringArray0.length; i++) {    values.add(myStringArray0[i]); }

Answer 5

遍历数组并将字符串添加到列表中。

int index = 0;

List<String> myList = new ArrayList<>();

List<ArrayList<String>> listlist = new ArrayList<>();

for (index = 0; index < mystringArray0.length, index++)

{

   myList.add(mystringArray0[index]); 

}

listlist.add(mylist);
