Trying to call an API URL from a Java application, I'm having problems accessing the contents of the URL.

I can access other sites through my program but not the Stack Exchange site.
But I can call the URL directly from the browser and get data. 

This is my program and output is in encrypted form.  I want to get in a normal format.

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

    public class URLServlet {

        public static void main(String[] args) {
            try {
            URL urldemo = new URL("http://api.stackexchange.com/2.1/questions/1346?site=health.stackexchange.com&filter=withbody");
            URLConnection yc = urldemo.openConnection();
            yc.setDoOutput(true);
            System.out.println(yc.getContent()); 
            BufferedReader in = new BufferedReader(new InputStreamReader(
                    yc.getInputStream()));
            
            String inputLine;
            while ((inputLine = in.readLine()) != null)
                System.out.println(inputLine);
            in.close();
            }catch(Exception e) {
                System.out.println(e);
            }
          
            System.out.println("hello world");
        }
    }
