TIL: The brevity of Kotlin

I’ve started looking into JVM languages. As an exercise, I researched how to do a basic HTTP request - one trivial evaluation point of a language (i.e. how simply or comfortably this built-in feature is made available).

In Java, here’s one way to request a page:

import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.URL;
import java.io.InputStreamReader;
import java.io.BufferedReader;

public class Main {

    public static void main(String[] args) throws IOException {

        URL url = new URL("http://example.com");
        HttpURLConnection con = (HttpURLConnection) url.openConnection();
//      con.setRequestMethod("GET");    // this line is optional since GET is the default

        BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
        String inputLine;
        StringBuffer content = new StringBuffer();
        while ((inputLine = in.readLine()) != null) {




The following is one way to do it in Kotlin:

import java.net.URL

fun main(){

To be fair, I read that Kotlin was not built to be a “better Java” but I can see why some Java developers are interested in Kotlin.
