将此javascript数组转换为java

我在一个非常老的项目上用JavaScript创建了一个多维数组，现在我已经从JS转向Java。我正在开发一个LibGDX游戏，我需要这个java格式的数组，但我不知道如何使用

var merchants = [{
  name : 'Weapons Merchant',
  items : [
    {type: "weapon", cost: 250, name: "Claymore"},
    {type: "weapon", cost: 75,  name: "Dagger"},
    {type: "weapon", cost: 350, name: "Magic Staff"},
    {type: "weapon", cost: 150, name: "Sword"},
    {type: "weapon", cost: 125, name: "Bow"},
    {type: "weapon", cost: 125, name: "Crossbow"},
    {type: "weapon", cost: 5,   name: "Arrow"},
    {type: "weapon", cost: 15,  name: "Bolt"}
  ]
}, {
  name : 'Armor Merchant',
  items : [
    {type: "clothing", slot: "head",     name: "Helmet"},
    {type: "clothing", slot: "head",     name: "Hood"},
    {type: "clothing", slot: "chest",    name: "Chestplate"},
    {type: "clothing", slot: "chest",    name: "Tunic"},
    {type: "clothing", slot: "chest",    name: "Robe"},
    {type: "clothing", slot: "leggings", name: "Legplates"},
    {type: "clothing", slot: "leggings", name: "Leggings"},
    {type: "clothing", slot: "leggings", name: "Undergarments"},
    {type: "clothing", slot: "feet",     name: "Boots"},
    {type: "clothing", slot: "feet",     name: "Armored Boots"}
  ]
},  {
  name: 'Material Merchant',
  items:  [
    {type: "material", name: "Leather", cost: 25},
    {type: "material", name: "Iron", cost: 50},
    {type: "material", name: "Steel", cost: 75},
    {type: "material", name: "Mythril", cost: 100},
    {type: "material", name: "Dragonbone", cost: 200}
  ]
}];

如何将其转换为Java

注意

由于我的移动助手有一个bug，我必须创建一个1d数组，如下所示：

public static List<CharSequence> intro = new ArrayList<CharSequence>();
intro.add("multiple add statements with strings");
final CharSequence[] introItems = intro.toArray(new CharSequence[intro.size()]);
        return introItems[number];

publicstaticlist intro=newarraylist（）；
add（“带字符串的多个add语句”）；
final CharSequence[]introItems=intro.toArray（新的CharSequence[intro.size（）]）；
退货项目[编号]；

因为它说

String[][]array=new String[5][5]

有错误“声明的意外结束”，所以如果可能的话，我希望使用我使用的格式回答。

如果您可以将数据稍微修改为纯JSON，可以这样做。我也不知道您是如何读取JS/JSON数据的，因此我假设您设法将其存储到解析代码中的字符串中：

jsonString

Merchant.Java

public class Merchant {
    private String name;
    private List<Item> items;
    /* Getters/Setters */
}

public class Item {
    private String name;
    private String type;
    private String slot;
    private int cost;
    /* Getters/Setters */
}

解析代码

//使用任何合适的方法读入字符串。
字符串jsonString=。。。；
//使用Jackson解析
ObjectMapper mapper=新的ObjectMapper（）；
List List=Arrays.asList（mapper.readValue(
jsonString，
商户[]类
);

如果希望将数据保留为数组，只需省略Arrays.asList（）调用即可

如果无法将代码修改为JSON，可以使用来解析旧的JS代码。

问题是，我们不知道如何存储数据。在这段javascript代码中，每个元素都是一个具有不同属性的对象。但是使用Java，您必须创建每个对象将表示的类。或者，您可以将所有内容都存储在Strin中你打算做什么？

public class Item {
    private String name;
    private String type;
    private String slot;
    private int cost;
    /* Getters/Setters */
}

// Read in the String using whatever means is appropriate.
String jsonString = ...;

// Parse using Jackson
ObjectMapper mapper = new ObjectMapper();
List<Merchant> list = Arrays.asList(mapper.readValue(
    jsonString,
    Merchant[].class
);
