질문

안녕하세요 저는 팀용 앱을 개발하고 싶지만이 오류가 발생합니다.

내 코드는 다음과 같습니다.

package de.tbprivi.mgde.Home;

import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
import org.json.simple.parser.ParseException;

import javax.swing.*;
import java.awt.*;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;

public class Home {

 public JFrame frame;
 private JSONParser parser;

 public Home(){

    frame = new JFrame();
    frame.setTitle("Miners-Games.de - TEAM APP");
    frame.setSize(700,500);
    frame.setVisible(true);
    frame.setLocationRelativeTo(null);

    try {
        getEventData();
    } catch (IOException | ParseException e) {
        e.printStackTrace();
    }

 }
 private void getEventData() throws IOException, ParseException {

    Object obj = parser.parse(new InputStreamReader(new URL("http://mylink.com/events.json").openStream()));

    JSONObject file = (JSONObject) obj;

    file.get("events");

  }
}

org.json.simple 라이브러리를 사용하고 있습니다.

문제 는 작동하는 것보다 내 공개 정적 void main () 에서 Home home = new Home ()이 아닌 getEventsdata ()를 호출 하는 것입니다.

도움을 주셔서 미리 감사드립니다 :)
