Question

我在JSONObject中遇到编译错误：

构造函数JSONObject（String）未定义

import org.json.JSONArray;  
import org.json.JSONObject;        
import java.io.Serializable;   
import java.util.ArrayList;  

public class ResultList implements Serializable   
{            
    private ArrayList<JSONObject> parliaments;

    public ResultList(ArrayList<JSONObject> data) {
        this.parliaments = data;
    }

    public ArrayList<JSONObject> getParliaments() {
        return this.parliaments;
    }
}

虽然代码仅根据JSON文档

Answer 1

    BufferedReader br;
    try {
        br = new BufferedReader(new FileReader("json.json"));
        StringBuilder sb = new StringBuilder();
        String line = br.readLine();
        while (line != null) {
            sb.append(line);
            line = br.readLine();
        }
        JSONObject jsonObj = new JSONObject(sb.toString());
        System.out.println(jsonObj);
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

如果找不到文件，您应该处理异常。我认为这适合你。
