How to validate a URLs status

I have excelsheet named as Validationstatuscode.xlsx which consists of list of URLs on Column A of sheet 1. I want to validate all URLs which show http status 200 or 400. Till now i've used http://httpstatus.io/ to validate 100 URLs at 1 shot but now the count has increased. So is there possible in java to validate the URLs? Though i've knowledge in java but dont know how to do this?

You can use java.net.HttpURLConnection for this as in the sample below. The key here is the getResponseCode method that will return the HTTP code, i.e. 200, 400... .

package so;

import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;

public class HttpRequest {

    private int getWebPageStatus(String url) {

        HttpURLConnection con = null;
        try {
            con = (HttpURLConnection) new URL(url).openConnection();
            return con.getResponseCode();

        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (con != null) {
                con.disconnect();
            }
        }

        return -1;
    }

    public static void main(String[] args) {
        HttpRequest request = new HttpRequest();

        System.out.println("https://login.yahoo.com  :" + request.getWebPageStatus("https://login.yahoo.com"));
        System.out.println("https://www.google.co.in :" + request.getWebPageStatus("https://www.google.co.in"));
        System.out.println("https://www.gmail.com    :" + request.getWebPageStatus("https://www.gmail.com"));
        System.out.println("https://xyz.co.in        :" + request.getWebPageStatus("https://xyz.co.in"));
    }

}
