[HELP] URLconnection output problem....

Question

Good evening, i am having a big problem on writting to the URL connection, after writing and reading to it.
This is my code
    static void conn (String []ficheiros, String[]refresh ) throws Exception
          contentor[] array = new contentor[ficheiros.length];
          int j=0;
          URL url = new URL("http://ssh:"+porto);
          URLConnection connection = url.openConnection();
          connection.setDoOutput(true);
          PrintWriter out = new PrintWriter(connection.getOutputStream());
          out.write(.....);
          out.close();
          BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
          String inputLine;
          inputLine=in.readLine();
          System.out.println("Out of input");
          in.close();
          URLConnection connection2 = url.openConnection();
          connection2.setDoOutput(true);
          PrintWriter out2 = new PrintWriter(connection2.getOutputStream());
          out2.write("Hello World")
     }I don't know if i can do this last step, but i really wanted to send another output to the server :( and he simply ignores!

Answer 1

My problem is that I don't know or have any idea how to make the output so it will show all the numbers in between, my ouput it only show the first 3 number, 1 8 and 9Hello and welcome to the forum. First and foremost, please use code tags when posting code here so that your code will retain its formatting and thus will be readable -- after all, your goal is to get as many people to read your post and understand your code as possible, right?
To do this, highlight your pasted code (please be sure that it is already formatted when you paste it into the forum; the code tags don't magically format unformatted code) and then press the code button, and your code will have tags.
Another way to do this is to manually place the tags into your code by placing the tag [code] above your pasted code and the tag [code] below your pasted code like so:
[code]
  // your code goes here
  // notice how the top and bottom tags are different
[/code]For instance, here is your code with tags:
import javax.swing.JOptionPane;
public class Necklace {
   public static void main(String[] args) {
      int f, s, sum, n, p;
      String first = JOptionPane.showInputDialog("Enter first number:");
      String second = JOptionPane.showInputDialog("Enter second number:");
      f = Integer.parseInt(first);
      s = Integer.parseInt(second);
      sum = f + s;
      n = sum % 10;
      p = s;
      while (!(p == f && n == s))
         sum = n + p;
         p = n;
         n = sum % 10;
      String output = f + "" + s + "" + ++n + "";
      JOptionPane.showMessageDialog(null, output, "Necklace",
               JOptionPane.INFORMATION_MESSAGE);
}Next, you can declare your output String before the while loop, and then concatonate a new int on to this inside the loop. Perhaps an even better way is to use a StringBuilder object.
