WiSheild/Aruino/Java Help!

Hello, i am new to the wisheild, and i have gotten all the sample sketches to work. i am having trouble finding documentation on how everything works with programing it. i understand that you have to set up a connection, and give it secure/non secure yata yata yata. what im confused about is

void setup()
{
      WiFi.init();
}

// This is the webpage that is served up by the webserver
const prog_char webpage[] PROGMEM = {"HTTP/1.1 200 OK\r\nContent-Type: text/html\r\n\r\n<center><h1>Hello World!! I am WiShield</h1><form method=\"get\" action=\"0\">Toggle LED:<input type=\"submit\" name=\"0\" value=\"LED1\"></input></form></center>"};

void loop()
{
      WiFi.run();
}

stuff like that. i know theat the Wfi.run(); and wifi.init(); are called from webserver.c and i can get how this simple version works. i do not get how stuff like this

boolean states[3]; //holds led states
char stateCounter; //used as a temporary variable
char tmpStrCat[64]; //used in processing the web page
char stateBuff[4]; //used in text processing around boolToString()
char numAsCharBuff[2];
char ledChange;

void boolToString (boolean test, char returnBuffer[4])
{
  returnBuffer[0] = '\0';
  if (test)
  {
    strcat(returnBuffer, "On");
  }
  else
  {
    strcat(returnBuffer, "Off");
  }
}

void printStates()
{
        for (stateCounter = 0 ; stateCounter < 3; stateCounter++)
        {
            boolToString(states[stateCounter], stateBuff);
           
            Serial.print("State of ");
            Serial.print(stateCounter);
            Serial.print(": ");
            Serial.println(stateBuff);
        } 
}

void writeStates()
{
        //set led states
        digitalWrite(ledPin1, states[0]);
        digitalWrite(ledPin2, states[1]);
        digitalWrite(ledPin3, states[2]);
}

// This is our page serving function that generates web pages
boolean sendPage(char* URL) {
  
  Serial.println("Page printing begun");
  
    printStates();
    writeStates();
    
  //check whether we need to change the led state
  if (URL[1] == '?' && URL[2] == 'L' && URL[3] == 'E' && URL[4] == 'D') //url has a leading /
  {
    ledChange = (int)(URL[5] - 48); //get the led to change.
    
    for (stateCounter = 0 ; stateCounter < 3; stateCounter++)
    {
      if (ledChange == stateCounter)
      {
        states[stateCounter] = !states[stateCounter];
            Serial.print("Have changed ");
            Serial.println(ledChange);
      }
    }
    
    //after having change state, return the user to the index page.
    WiServer.print("<HTML><HEAD><meta http-equiv='REFRESH' content='0;url=/'></HEAD></HTML>");
    return true;
  }
  
  if (strcmp(URL, "/") == false) //why is this not true?
   {
      WiServer.print("<html><head><title>Led switch</title></head>");
    
      WiServer.print("<body><center>Please select the led state:<center>\n<center>");
      for (stateCounter = 0; stateCounter < 3; stateCounter++) //for each led
      {
        numAsCharBuff[0] = (char)(stateCounter + 49); //as this is displayed use 1 - 3 rather than 0 - 2
        numAsCharBuff[1] = '\0'; //strcat expects a string (array of chars) rather than a single character.
                                 //This string is a character plus string terminator.
        
        tmpStrCat[0] = '\0'; //initialise string
        strcat(tmpStrCat, "<a href=?LED"); //start the string
        tmpStrCat[12] = (char)(stateCounter + 48); //add the led number
        tmpStrCat[13] = '\0'; //terminate the string properly for later.
    
        strcat(tmpStrCat, ">Led ");
        strcat(tmpStrCat, numAsCharBuff);
        strcat(tmpStrCat, ": ");
        
        boolToString(states[stateCounter], stateBuff);
        strcat(tmpStrCat, stateBuff);
        strcat(tmpStrCat, "</a> "); //we now have something in the range of <a href=?LED0>Led 0: Off</a>
    
        WiServer.print(tmpStrCat);
      }

        WiServer.print("</html> ");
        return true;
   }
}

void setup() {
  // Initialize WiServer and have it use the sendMyPage function to serve pages
  pinMode(ledPin1, OUTPUT);
  pinMode(ledPin2, OUTPUT);
  pinMode(ledPin3, OUTPUT);

  Serial.begin(9600);
  WiServer.init(sendPage);
  states[0] = false;
  states[1] = false;
  states[2] = false;
}

void loop(){
  // Run WiServer
  WiServer.server_task();

  delay(10);
}

works. i cannot find a place to reference anything. and async labs has been little to no help to me at all. also, i am wondering if it is possible, to eliminate the html/reload pags thing and have say, a live feed camera apended to a java program the you can drive the camera around through the program and not have to use a browser. i do beileive that tcp is involved? i would be in great dept if you could point me in the right direction and NOT the god damn async wiki ists completly useless and does not help me. please help, i am begging you.

An example of the begining of what i want to do:
I can simple plug a ping seansor into my arduno and plug it into the computer, then easly program my arduino to call a ping function and then read the value of the seansor, then through some conversion math i can convert that value to inches and serial print it and be able to see the distance the ping is reading on the serial monitor. then add the wisheild to the arduino and hook up the ping, and through some slightly more complex code be able to still see the ping distance over serial monitor, now just completly wirelessly. first off, how do i acomplish that and where do i start?

Well, java can seamlessly use your systems wifi capabilities... so that server example still holds merrit. Remember that the internet is nothing more than a socket layer with a software protocol (http - HyperText Transfer Protocol) on top, there is no reason why you can't make a (http) socket connection from java to your wifi shield.

I do hope you mean your camera is a wireless IP camera, since the arduino won't be able to feed a video stream over wifi (it can't even do it over a wire, the constraint is in the arduino's processing speed and memory limitations).
