I have read some answers like
Simplest way to read JSON from a URL in Java
but it did not work.
Okay, here is my code:
package day1;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Scanner;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
public class MainGet {
public static void main(String[] args) {
try {
URL url = new URL("https://api.covid19api.com/summary");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
conn.connect();
//Getting the response code
int responsecode = conn.getResponseCode();
if (responsecode != 200) {
throw new RuntimeException("HttpResponseCode: " + responsecode);
} else {
String inline = "";
Scanner scanner = new Scanner(url.openStream());
//Write all the JSON data into a string using a scanner
while (scanner.hasNext()) {
inline += scanner.nextLine();
}
//Close the scanner
scanner.close();
//Using the JSON simple library parse the string into a JSON object
JSONParser parse = new JSONParser();
JSONObject data_obj = (JSONObject) parse.parse(inline);
//Get the required object from the above created object
JSONObject obj = (JSONObject) data_obj.get("Global");
//Get the required data using its key
System.out.println(obj.get("TotalRecovered"));
JSONArray arr = (JSONArray) data_obj.get("Countries");
for (int i = 0; i < arr.size(); i++) {
JSONObject new_obj = (JSONObject) arr.get(i);
if (new_obj.get("Slug").equals("albania")) {
System.out.println("Total Recovered: " + new_obj.get("TotalRecovered"));
break;
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
I want an example that can run in Eclipse. I have installed Gson and am using JDK11.
Here is my URL:
I want to read it into Java.
Thanks so much.

I think I have added org.json to the path, but still have errors.
