Dont understand anything

hi,
This is priya and need some urgent help... i am pursuing engineering and as a part of the curriculum created an application using application exppress.
Now, the problem is that i have export an application as an sql file and wanted to view the script for the whole application...unfortunately couldn't understand anything in it.
My university review is day after tmrw...and it is expected that i explain the code..and i thought that i will explain the sql script file for the application that i exported.
How do i know wht certain terms mean...for eg...
set define off
set verify off
set serveroutput on size 1000000
set feedback off
WHENEVER SQLERROR EXIT SQL.SQLCODE ROLLBACK
begin wwv_flow.g_import_in_progress := true; end;
prompt Set Credentials...
begin
-- Assumes you are running the script connected to sqlplus as the owner (parsing schema) of the application or as the product schema.
wwv_flow_api.set_security_group_id(p_security_group_id=>12575620894329819);
end;
begin wwv_flow.g_import_in_progress := true; end;
begin
select value into wwv_flow_api.g_nls_numeric_chars from nls_session_parameters where parameter='NLS_NUMERIC_CHARACTERS';
end;
begin execute immediate 'alter session set nls_numeric_characters=''.,''';
end;
begin wwv_flow.g_browser_language := 'en-us'; end;
prompt Check Compatibility...
begin
-- This date identifies the minimum version required to import this file.
wwv_flow_api.set_version(p_version_yyyy_mm_dd=>'2005.05.01');
end;
prompt Set Application ID...
begin
-- SET APPLICATION ID
wwv_flow.g_flow_id := 134;
wwv_flow_api.g_id_offset := 0;
null;
end;
couldn't understand anything from this...what to do...please help!!!!

Well, unless you have an understanding of SQL of PL/SQL, you won't understand anything.
But that's also part of the beauty of Application Express as well. You really don't have to know SQL or PL/SQL to develop a working application, though having that knowledge can make the whole process easier and also allows you to create more "sophisticated" applications. (Not sure if sophisticated is really the right word though, maybe complex?)
Anyway, instead of trying to learn SQL and PL/SQL in a day, a better approach may be to explain that with Application Express you don't need to know the code, and instead focus on your application itself, what it does and how it does it.

  • Dont understand what i should put down for host name for creating an email account?

    Dont understand incoming and outcoming server. dont know what to put for host name.
    can someone help?

    Do you have your email account set up on your computer e.g. on Outlook on a PC or Mail on a Mac ? If you have then you should be able to sync the settings from that to your iPad via the Info tab when connected to your computer's iTunes. Or you could just look at the settings for the account on your computer's email program and copy them over to the iPad manually.
    The incoming and outgoing server names are the servers that your email provider uses for your account to recieve (incoming) and send (outgoing) emails. A lot of accounts should be covered by the options that are listed on the 'Add Account' screen - for my Yahoo based accounts I just chose Yahoo! and the settings were set for me. If you have an account that isn't covered by those types then you could try logging into your account via a browser and see if they have any help for what settings you need to use. Different account providers have different settings, so if your can't find anything on your provider's site if you say on here who your provider is there might be somebody else here who has the same provider and can tell you what settings to use.

    Maybe you should get new friends.
    I'm not sure that recovery mode works when you have to trust the computer, but did you try it?
    If you can't update or restore your iOS device - Apple Support
    If that won't work, perhaps you can use Find my iPhone from a computer in your iCloud.com account to erase the device.
    iCloud: Erase your device - Apple Support
    This has nothing to do with the Find my iPhone app being installed on the phone, but you do have to have Find my iPhone activated in the iCloud settings on the phone.

    (1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
    http://majorgeeks.com/download.php?det=4459
    (2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
    (3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
    (4) In the list of programs that appears in CleanUp, select any Apple Software Update entries and click "Remove", as per the following screenshot:
    (5) Quit out of CleanUp, restart the PC and try another iTunes install using an iTunesSetup.exe (or iTunes64Setup.exe) downloaded from the Apple Website:
    http://www.apple.com/itunes/download/
    Does it go through properly this time?

  • I dont understand creating classes they seem a waste of time and efficiency

    I dont understand why we would want to create classes with constructors and get and set statements... I know that VB and Java did not create these just to have us writing extra code so I am missing something in my thinking.
    I read about data hiding and that I understand I guess...but everytime my professors want me to create a class then create an object from that class to access it I dont really get it. I know how to do the basics of it but I can do all of it in my main or the primary class whats the benefit of creating a whole entire class such as the following?
    Everytime I get an assignment and they are like create a class and I try to rack my head for a good idea but the nearest analogy I can come up with is this... creating your own class seems like one of those old straws you drink out of with all the loops, yes you can make it go around in a big loop but why waste time? you want to get to point A to point B so create the most efficient way to get there if possible.
    I am sure the problem is I am not seeing something and there is some logic missing but I just am getting irritated as I am not seeing it and I am finding it, its like I add an extra obstacle course to my code for no other reason than to run through a bunch of extra tasks that I could perform in my main class or main.
    input is welcome to help me arrive at some type of enlightenment thanks
    Class may not be the correct wording for this as I know we have to have a class but what I mean is a non application class. The class I have below goes with another class that actually does a lot of stuff but I am forced to push data through this class that basically does nothing but run water through some different pipes if you will. To me thats a waste when I can do everything in my original class which was called menu that I am messing with and that creates an array for a user who wants to keep a list of his items and prices of those items in inventory.
    public class Item
    private String itemName;
    private double itemPrice;
              public Item()
    public Item (String item, double price)
    setName(item);
    setPrice(price);
    public String getName()
         return itemName;
    public void setName(String item)
         itemName = item;
    public double getPrice()
         return itemPrice;
    public void setPrice(double price)
         itemPrice= price;

    What I was plugging into it and please forgive the code as its not finished... (I am still messing with it) its just for learning and I am required to have certain parts in the Item Class and Certain parts in the Menu class..... But you it pushes through the input to the java bean.... in a case like this I just dont see the need for doing it not that I can think of anyway.
    import java.util.Scanner;//my imports for scanner so can read from the screen
    import java.util.*;//imports for my array I used astrix to just import it all as the book said it does not have any negative affects.
    public class Menu //My application class Menu that contains my main
         public static void main(String[] args)//Main method
              final int NUMBER_Of_Elements = 30; //created a symbolic constant so that I only have to change the constant
              //to edit the size of the array if I should want to change it.
              Item[]inventory = new Item[NUMBER_Of_Elements];//I create a new array object with the constant as the number of elements.
              Scanner sc = new Scanner (System.in);//created object from the scanner class used to get input from the console screen.
              System.out.println("Please enter Item on first line and price on second line.");//outputted text to prompt user and give instructions.
              System.out.println("Enter STOP to exit");//instructions on how to exit the program. I would have rather used a different
              //word than stop here. If my choice I would have used "exit" as its more widely used and to promote uniformity.
              int count;//count variable used to count my loops very important as we use it to control our arrays and loops here.
              double price;//our variable that we plug in values from the user via the console.
              String item;//same as previously mentioned for the "price"
                        System.out.println("Wings Coffee Shop Menu");
              System.out.println("");
              System.out.println("Menu Item Price");
              for (count=0; count<inventory.length; ++count)//This is our for loop it uses the length method to control how many times
              //it runs. In this case inventory.length = 30 elements so would run 30 times unless it stopped early.
                   item = sc.nextLine();//reads the input from console into the item variable.
                   if(item.equalsIgnoreCase("STOP"))//if statement that states if = stop (ignores case sensitivity) then it will break out of the loop.
                   break;//the break command which is executed if the if statement is true.
                   price = Double.parseDouble(sc.nextLine());//
                   inventory[count]= new Item(item, price);
                   Item Call = new Item(item, price);
                   System.out.printf("%-13s %.2f\n", Call.getName(), Call.getPrice());
              System.out.println("Wings Coffee Shop Menu");
              System.out.println("");
              System.out.println("Menu Item Price");
    //           for(int x = 0; x < count; ++x)
    //           System.out.printf("%15s\n",inventory[x].toString());
    //                System.out.printf("%-13s %.2f\n", Call.getName(), Call.getPrice());
    //           String[] namesOfItems = {"Coffee", "Milk", "Soda", "Bagel", "Croissant", "Donut"};
    //           double[] prices = {3.99, 2.99, 2.49, 2.99, 2.49, 1.99};
    //           for(int x = 0; x < prices.length; ++x)
    //           System.out.printf("%-13s %.2f\n", namesOfItems[x], prices[x]);
    //           Item arrayPrice = new Item(); HOW COME I CANNOT CREATE THIS OBJECT?

  • My ipod was stolen and i need the serial number to denounce, but i dont have anything how i can get the number?

    If your iPod was the last device that you connected to and synced with your iTunes library, there is a chance you might be able to get the serial # to show up in the Device Connectivity diagnostic report. See here for instructions on running this test.
    iTunes for Windows: Device Connectivity Tests
    If you have previously registered the device with Apple, you can view it's serial # in your list of devices you have registered under your Apple ID.

  • Need Help! Passing an array of objects to a method, dont understand

    Hi, i need to make a method called public Server[] getServers() and i need to be able to see if specific server is available for use.
    I have this so far:
    public abstract class AbstractServer
    protected String serverName;
    protected String serverLocation;
    public AbstractServer(String name,String location)
    this.serverName=name;
    this.serverLocation=location;
    public abstract class Server extends AbstractServer
    public Server(String name,String location)
    super(name,location);
    public class CreateServers
    Server server[];
    public CreateServers()
    public Server create()
    for(int i=0; i<10; i++)
    server=new Server(" ", " "); //i was going to fill in something here
    return server;
    OK NOW HERE IS THE PROBLEM
    i have another class that is supposed to manage all these servers, and i dont understand how to do the public Server[] getServers(), this is what i have tried so far
    public class ServerManager()
    public Server[] getServers(Server[] AbstractServer)
    Server server=null; //ok im also confused about what to do here
    return server;
    in the end i need this because i have a thread class that runs the servers that has a call this like:
    ServerManager.getServers("serverName", null);
    Im just really confused because i need to get a specific server by name but i have to go through AbstractServer class to get it
    Any help?

    thanks for replying...
    ok ill remove the Server.java one to be
    public class Server extends AbstractServer
         public Resource(String name,String locaton)
              super(name,location);
    ok so inside ServerManager.java i should have something like
    ArrayList servers;
    public ServerManager()
    servers=new ArrayList();
    ok but i still dont get how to use that in a method
    say if i put it like this
    public getServers()
    //populate server list in here??????
    ok im still lost...
