    Default 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();
            }
     
    }
