从网站获取Json，反序列化并输出到控制台(什么是输出？)

import requests
import json

response = requests.get('https://example.com/api/data')
data = json.loads(response.text)
print(data)

fetch('https://example.com/api/data')
  .then(response => response.json())
  .then(data => console.log(data));

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

URL url = new URL("https://example.com/api/data");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");

BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String line;
StringBuilder response = new StringBuilder();
while ((line = reader.readLine()) != null) {
    response.append(line);
}
reader.close();

String json = response.toString();
System.out.println(json);
