I just want to get the HTML code of a webpage out as a String.
I tried it with java's URLConnection + InputStream:
The first times it works (HTML was printed on the console) but after wards it didn't do anything and it slows down the computer...
What happened? I don't really know java.net Classes and what happens behind the scenes... Maybe someone knows and could help?


Here the code:

import java.net.*;
InputStream urlStream;
boolean alreadyconnected = false;

String content;

//URLConnection c;
void draw(){


if(alreadyconnected == false ){
 try{
 

   URL url = new URL("url");
// i can't post a link here. Please enter a random URL
   URLConnection c;
   
   
     
   c = url.openConnection();
   urlStream = url.openStream();
   
   
   byte b [] = new byte[1000];
   int numRead = urlStream.read(b);
    content = new String(b,0,numRead);
   while(numRead != -1){
      numRead  = urlStream.read(b);
      if(numRead != -1){
        String newContent = new String (b, 0, numRead);
        content += newContent;
       
      }
     
   }
   
   if(numRead == -1){
   println(content);
   urlStream.close();
   alreadyconnected = true;
   }
   

 


 }
 catch(IOException e){
   println("doesn't work");}
 

}

}

Not surprising given the code you show...
alreadyconnected boolean is here to ensure the HTML is downloaded only once.

Or do you mean first runs of the sketch

Well, the interest of Processing is to insulate as much as possible from Java for the most common operations.
So perhaps you can proceed as Quark suggested and use loadStrings().
If it is not suited to your needs, you should explain why and how the Java code you use brings some advantages.
