Make a function to see if someone is on hypixel

[ghost]

I was thought that maybe there could be a function that returns a boolean that checks if someone is on hypixel. For example:
(This is really bad code but I made it really quick with a video and could definitely be improved, but it works)

public static boolean getOnlineStatus(UUID playerUUID) {
		final char qutation = '"';
		final String successLine = "{" + quotation + "success" + quotation + ":true";
		final String notSuccessLine = "{" + quotation + "success" + quotation + ":false";
		final String onlineTrue = "{" + quotation + "online" + quotation + ":true";
		final String onlineFalse = "{" + quotation + "online" + quotation + ":false";
		BufferedReader reader;
		String line;
		final StringBuffer responseContent = new StringBuffer();
		try {
			URL url = new URL("https://api.hypixel.net/status?key=" + apiKey + "&uuid=" + playerUUID);
			connection = (HttpURLConnection) url.openConnection();
			
			connection.setRequestMethod("GET");
			connection.setConnectTimeout(5000);
			connection.setReadTimeout(5000);
			
			int status = connection.getResponseCode();
			if(status > 299) {
				reader = new BufferedReader(new InputStreamReader(connection.getErrorStream()));
				while((line = reader.readLine()) != null) {
					responseContent.append(line);
				}
				reader.close();
			}else {
				reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
				while((line = reader.readLine()) != null) {
					responseContent.append(line);
				}
				reader.close();
			}
			
			if(responseContent.toString().contains(notSuccessLine)) {
				return false;
			}
			
			if(responseContent.toString().contains(onlineTrue)) {
				return true;
			}else if(responseContent.toString().contains(onlineFalse)) {
				return false;
			}
			
		} catch(IOException e) {
			e.printStackTrace();
		}
		finally {
			connection.disconnect();
		}
		return false;
	}

Is there a reason you're not using the Java API wrapper (found in this repo)? If you were, you could simplify it down to just

boolean isOnline = api.getStatus(playerUUID).get().getSession().isOnline();

Oh, didn't notice that! Thanks

No problem, just be sure to handle ExecutionExceptions since API errors will be wrapped in those.

You can already check if someone is online, the URL: https://api.hypixel.net/status
It returns something like this:
{
"success": true,
"uuid": "ad8fefaa8351454bb739a4eaa872173f",
"session": {
"online": true,
"gameType": "string",
"mode": "string",
"map": "string"
}
}
