You can use Spring's RestTemplate to get the response as String, e.g.:
RestTemplate restTemplate = new RestTemplate();
String response = restTemplate.getForObject("https://www.instagram.com/ihanan95/?__a=1", String.class);
System.out.println(response);
If you are not allowed to use third party libaries then you can do the same with URLConnection, e.g.:
URLConnection connection = new URL("https://www.instagram.com/ihanan95/?__a=1").openConnection();
try(Scanner scanner = new Scanner(connection.getInputStream());){
String response = scanner.useDelimiter("\\A").next();
System.out.println(response);
}

Read JSON file from remote website.
Example:
URL url = new URL("https://www.instagram.com/ihanan95/?__a=1");
JSONTokener tokener = new JSONTokener(url.openStream());
JSONObject obj = new JSONObject(tokener);
JSONObject data = obj.getJSONObject("user");
String message = data.getString("message");
