Question

我想遍历数组列表。我也确实想更改列表的每次迭代的value。例如：

    for (int i = 0; i < value.length; i++) {
        System.out.println(i+1, list.value[i]);
    }

我的value数组如下所示：

String [] value = {"identifier", "hyperlink", "children", "afterItemList", "beforeItemList"};

列表声明：

public class ItemAndAttributeObject {
String hyperlink;
String identifier;
String title;
String parentUniqueUrl;
String functionType;
ArrayList<String> children;
ArrayList<String> attributeList;
ArrayList<String> afterItemList;
ArrayList<String> beforeItemList;
public ItemAndAttributeObject(String title, String identifier, String hyperlink, String parentUniqueUrl, String functionType, ArrayList<String> children, ArrayList<String> attributeList, ArrayList<String> afterItemList, ArrayList<String> beforeItemList) {
    this.hyperlink = hyperlink;
    this.identifier = identifier;
    this.title = title;
    this.children = children;
    this.functionType = functionType;
    this.parentUniqueUrl = parentUniqueUrl;
    this.attributeList = attributeList;
    this.afterItemList = afterItemList;
    this.beforeItemList = beforeItemList;
}

我想：

像这样打印出来：

//FIRST ITTERATION
for (int i = 0; i < value.length; i++) {
    System.out.println(i+1, list.identifier);
}

//SECOND ITTERATION
for (int i = 0; i < value.length; i++) {
    System.out.println(i+1, list.hyperlink);
}

//THIRD ITTERATION
for (int i = 0; i < value.length; i++) {
    System.out.println(i+1, list.children);
}

//FOURTH ITTERATION
for (int i = 0; i < value.length; i++) {
    System.out.println(i+1, list.afterItemList);
}

这可能吗？

Answer 1

for (int i = 0; i < value.length; i++) {
    System.out.println(list.value[i]);
    value[i] = "new";
}
