我想从json字符串中提取一个值,该值在String中多次出现。在我的代码中,我只获取了该String.I的最后一次出现我发布了我的JSON字符串和Java代码如何从json字符串中提取值
public class JsonDemo{
public static void main(String args[])
// let's read
readJson("book.json");
}
public static void readJson(String file) {
JSONParser parser = new JSONParser();
try {
System.out.println("Reading JSON file from Java program");
FileReader fileReader = new FileReader(file);
JSONObject json = (JSONObject) parser.parse(fileReader);
for(int i=0;i<json.size();i++){
String title = (String) json.get("title");
System.out.println("title: " + title);
}
/* String title = (String) json.get("title");
String author = (String) json.get("author");
Long price = (Long) json.get("price");
System.out.println("author: " + author);
System.out.println("price: " + price);
JSONArray characters = (JSONArray) json.get("characters");
Iterator i = characters.iterator();
System.out.println("characters: ");
while (i.hasNext()) {
System.out.println(" " + i.next());
}*/
} catch (Exception ex) {
ex.printStackTrace();
}
}
这是我的JSON字符串

我只得到了“人·波特与混血王子”的价值,但我想这两个“哈利·波特与混血王子“和”曼波特与混血王子“
可以在管理{ “称号”:...},{ “称号”:.... 。} ??看到我编辑的帖子 – Subho
@Madhushan我可以用你的代码获得intAvailability吗?看到我更新的json – Subho
是的。它可以管理...为什么你不试试? –
