Thread: Managing Http requests

Hello, i would like some enlightment with my project.
I am trying to create a class that will be able to create and sent http requests (GET of POST). I also want it to be able to change some http headers and sent the request. I am a bit confused about the order in which the statements should be executed to have the results. For example i saw some tutorials put first open connection and then set the request type.
I thought the order should be set request type,set headers, openconnection.
I am using the HttpURLConnection.

Here is what i have done so far:
import java.net.*; import java.io.*; public class HTTP { private String - Pastebin.com

import java.net.*;
import java.io.*;
 
public class HTTP {
 
        private String baseURL;
        private String path;
        private String fullPath;
        private HttpURLConnection http;
 
        public HTTP(String url){
                this.fullPath=url.indexOf("http://")==0?url:"http://".concat(url);
                this.baseURL=getBaseUrl(url);
                this.path="";
                this.openConnection();
        }
 
        public void addHeaders(String[] headers,String values){
                for(int i=0;i<headers.length;i++);
 
        }
 
        public void changePath(String path){
                this.path=path;
                this.fullPath=this.baseURL.concat(path);
                this.openConnection();
        }
 
        public static String getBaseUrl(String url){
                String val="http://";
                if(!url.contains("http://")) url="http://".concat(url);
                String results[]=url.split("/");
                if(results.length>=3) return val.concat(results[2]);
                return "";
        }
 
        private void openConnection(){
                try {
                URL u = new URL(this.fullPath);
                this.http = (HttpURLConnection) u.openConnection();
              }catch (MalformedURLException ex) {
                System.err.println(this.fullPath + " is not a URL I understand");
              }catch (IOException ex) {
                  System.err.println(ex);
              }      
        }
 
        public void setHeader(String header,String value){
                this.http.setRequestProperty(header, value);
        }
 
        public void addHeader(String header,String value){
                this.http.addRequestProperty(header, value);
        }
 
        public void printHeaders(){
                for (int j = 1; ; j++) {
                  String header = this.http.getHeaderField(j);
                  String key = this.http.getHeaderFieldKey(j);
                  if (header == null || key == null) break;
                  System.out.println(this.http.getHeaderFieldKey(j) + ": " + header);
                }
        }
 
        public static void main(String[] args) {
                        HTTP h=new HTTP("http://google.com/agsa");
                        h.setHeader("Referer", "wwwa.ga.a");
                        h.printHeaders();
        }
 
}

I have found that using apache HttpClient might be easier.
Thank you
