Methods... What to do...?

1. Describe the structure of a typical method making reference to its accessibility, return value, passed parameters, its begin/end delimiters and the method call itself:
public void paint (int x, int y) {
paint(100, 100);
Explain the benefits of encasing a block of software code within a method.
What a beautiful question... And i have answered most of it...
I just need a help with explaining the delimeters... Your answer will be fully referenced in my assignment, I only need to know what delimeters are... can anybody help?
Thanks...

"... its begin/end delimiters and the method call itself:"
As well as defining a
doThis(){
BLOCK
OF
CODE
the delimiters also perform the function of a flow of execution
eg;-
<A Program for a user data form>
1. Declare variables that need access all functions such as Strings, ints, buttons and textfields
2. {
[CodeBlock1]
initialise active variables and set up GUI with the methods init() =java.awt or javax.swing [CodeBlock1]
and paint() (
[CodeBlock2]=java.awt.Graphics etc [CodeBlock2]
3. function waits for a call
public void checkdata(){
CHECK
DATA
CODE
if (!(correct)) tellClientWhatsWrong()
else processData()
public void tellClientWhatsWrong(){
CODE
public void processData(){
PutItAll
TogetherCode
nowThatItsready
SaveData()
public void SaveData(){
CODE to save data to file
Each block of code defines clearly its own method() -(as indicated by the parenthisis() )
This makes it easier to read /understand / amend or correct -BUT ALSO there is a logical flow to the program, in this a example a user form, so all of the methods don't do anything until the user does something
So we also have a function called
actionPerformed(){
if(condition=user hits the 'send' button){
checkdata()
So it goes along the daisy chain of functions above from the checkData() method to the processData() method and then to the saveData() method
= LOGICAL PROGRAMMING STRUCTURES!

HT2731 i used debit card for purchasing i dont have credit card now its showing your payment method is decline use another payment method what shoul i do i dont have credit card

i used debit card for purchasing i dont have credit card now its showing your payment method is decline use another payment method what should i do i dont have credit card or any another account

I don't think that debit cards are still accepted as a valid payment method - they are not listed on this page and there have been a number of posts recently about them being declined. You could try contacting iTunes support and see if they can help, but I don't think you will be able to use a debit card : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page
Are iTunes gift cards available in your country ? They are not available in all, and they are country-specific (they can only be used in their country of issue), but if there you could possibly use them as your payment method.

HT201209 i cant register my debit card to apple id...........when i am tring to register........it shows your payment method was delclined please enter a valid payment method what should i do???

i cant register my debit card to apple id...........when i am tring to register........it shows your payment method was delclined please enter a valid payment method what should i do???

If it's a debit card then I don't think that they are still accepted as a valid payment method in all countries - from this page :
You may be able to use other payment types in your country, like debit and Maestro cards.
which implies that they are not accepted in all countries, and there have been a number of posts about them being declined.
Is the card then is it registered to exactly the same name and address (including format and spacing etc) that you have on your iTunes account, it was issued by a bank in your country and you are currently in that country ? If it is then you could check with the card issuer to see if it's them that are declining it, and if not then try contacting iTunes support and see if they know why it's being declined : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Account Management.
Or do you have a credit card that you could use instead ?

I Try registering my card in order to use the services of Itunes so that always appears refused payment method, what should I do?

If you are referring to a credit card and it being refused, then something is probably wrong with the entry of the card or your account information. It is not matching what is on file for your account. Generally this is the address field. Make sure it matches what you see on your bill exactly. Otherwise, you need tocontact iTunes support. http://www.apple.com/emea/support/itunes/contact.html

Java Virtual Machine "Could not find main method" what do i do?

Hi I'm very new to java and for my class we are to make an applet and make a class. I figured out how to do it but the Java Virtual Machine gives me an error when I go to run the applet."Could not find the main method. Program Will exit!" . I am using Jbuilder8 personal to compile the code. Using j2sdk1.4.0_03. Could someone tell me how to fix this? Or what I'm doing wrong?

Java Virtual Machine "Could not find main method" what do i do?
Ok Ok OK I got the solution for you ,this is what you do you put your hands inbetweenj you leggs and run around in a circle can scream me nuts me nuts me nuts are on fire,then come back and tell use if the problem is solved or not
Good luck hehehehe:P

Why is my payment method for itunes always declined? i used many mastercards but still it declines my payment method, what should I do?

apple is not accepting my payment method ,I also used many mastercards but it is always declining it is very annoying what should I do?

The quickest way to get an answer to this may be to contact your card issuer directly, it may be that they are having issues with their payment gateways. Also a good idea to do what Ralph9430 suggested as well though.

Static methods, what for?

What are static methods for? is there something that is not possible through methods associated with instances (non-static methods) ?

There are many examples of static mehods in the Java API. For example the Math or the System class. All methods in this classes are static. So you dont have to instantiate the system class. In fact it is even not possible to instantiate the System class. System is final and all Constructors are private.
Another use for static methods is the access to private static variables.

Calling method what is the proper way

hi fellows
i want to call a method but i need some help on that issu with or without instance of an object. like
package ch.fhnw.athene.ui.components;
import ch.fhnw.athene.ui.components.model.CPTabModel;
import ch.fhnw.athene.ui.components.model.CPTabpaneModel;
import ch.fhnw.athene.ui.components.model.CPToolbarModel;
i have add frame in CPTabmodel.
i add JButton in CPToolbarModel and actionlistener also.
the method
public void showframe(){/body of the method}
in CPTabpaneModel.
how can i call this when press button. or define the method static if i define static what happen with frame and button class these are also static or not.

I would think that using....
var theMask:MovieClip = myContainer.getChildByName("NAME-"+String(num));
would work, where you could use theMask to target it. Another approach to this would be to store each mask in an array so that you can just use the array to target them...
var maskArray:Array = new Array();
var myMask:MovieClip = new MovieClip();
maskArray[i] = myMask;
myContainer.addChild(myMask);
myContainer.mask = myMask;
Note: When you first name the object you should be converting i to a String as well... myMask.name = "NAME-"+String(i); unless i is already a String

Push Instance method : what to pass in TASK and Sync_mode

Hi All,
I have created a Push Instace method for a Backend Triggered DO. Now i want to know that what is to be passed in its import parameter Task and Sync_mode.
There are no possible values defined
Thanks & Regards,
Abhishek

Hi Abhishek,
Adding to the above reply,
Task is an optional parameter. If you do not specify a Task, the DOE will dynamically decided what to do with the data. If there is already data for the same key in the CDS it will update it. If there is no data for the same key, it will insert it.
Incase you want to delete the record, then you will have to specify the task as 'D' explicitly in the importing parameter otherwise its not needed.
Also,if you do not set the SYNC_MODE, the function module will be executed in queue and the name of the queue will end with '*CMP'. This is just for tracking purpose.
Best regards,
Vinodh.

FIFO costing method - what table ?

Hi all,
I got one child org. which is on FIFO costing method and I got the standard report from Oracle which show the total value of the item.
Now, I'm intend to write a report to show the details on what value the system will picked up individually when there is a move order/ issue that happened. What are the tables that involved when there is a move order/ issue for the item. I can see
mtl_cst_actual_cost_details which has new_cost, prior_cost & actual_cost. But when come to move order/issue the actual_cost was average up. I can't see the FIFO picking up ?
Please advise.

Please post this in the Order Management forum also if you havent done so already.

Protected methods, what did i do wrong?

Hi there, I'm trying to understand why I cant access a Protected Method from a library that I'm trying to use..
Some guidance would be great:
public class Registration {
//Create new instance of ConnectionBean
ConnectionBean conBean = new ConnectionBean();
public Registration() {
public void regUser() {
String server = JOptionPane.showInputDialog( "Enter Server address" );
InetAddress inetaddress;
try {
conBean.connect( inetaddress = InetAddress.getByName( server ));
catch( UnknownHostException unknownhostexception ) {
Object aobj[] = {
"Cancel", "OK"
int i = JOptionPane.showOptionDialog(null, "Retry Server?", server +
": Not Responding", -1, 2, null, aobj, aobj[1]);
if( i == 1 )
regUser();
System.out.println( "Cannot resolve " + server + ":" + unknownhostexception.toString ());
return;
catch( IOException ioexception ) {
Object aobj1[] = {
"Cancel", "OK"
int j = JOptionPane.showOptionDialog( null, "Cannot Connect to:",
server,-1, 2, null, aobj1, aobj1[1] );
if( j == 1 )
regUser();
System.out.println( "Cannot connect " + server);
return;
System.out.println( "Registering User" );
registrationProcess();
public void registrationProcess () {
InfoQueryBuilder iqb = new InfoQueryBuilder();
InfoQuery iq;
IQRegisterBuilder iqRegb = new IQRegisterBuilder();
IQRegister iqReg = new IQRegister( iqRegb );
try {
//Need to getXMLNS packet method getXMLNS() is protected
iqReg.getXMLNS();
catch ( InstantiationException e ) {
System.out.println( "Error in building Registration packet" );
String username = JOptionPane.showInputDialog( "Enter: Username" );
String password = JOptionPane.showInputDialog( "Enter: Password" );
The error as would be expected:
Registration.java:96: getXMLNS() has protected access in org.jabber.jabberbeans.Extension.IQRegister
iqReg.getXMLNS();
^
1 error
Appreciate the help!! :)

I tried to extend the class to make it a subclass of IQRegister (which holds the protected method) but I'm getting this error:
Reg.java:19: cannot resolve symbol
symbol : constructor IQRegister ()
location: class org.jabber.jabberbeans.Extension.IQRegister
public class Reg extends IQRegister {
^
1 error
Any ideas?
thanks

HT2534 I don't have the option of "none" on the seletion for pament methods, what do i do?

I have an iPhone 3G, it is 4.2.1 firmware and i can't select the "none" for pament selection in my apple ID settings. Please help me.

You need to ask Apple to reset your security questions; this can be done by clicking here and picking a method, or if your country isn't listed, filling out and submitting this form.
They wouldn't be security questions if they could be bypassed without Apple verifying your identity.

When I want to download an app it keeps saying payment type is not valid please enter new payment method, what do I do

When an app is free and it asks for account information which is correct why does it keep saying payment type invalid please choose another payment type.?

Maybe check with your bank and see if everything is ok with your account.
settings - appstore - view id - account info, then you can edit your payment.

What am I doing wrong with this method?

Ok I tried this for two hours and for some reason my variables from one method wont work with the other method what am I doing wrong?
public class Testing
private static void storage(String[] storage){
String retval= "";
for(int i=0;i!=storage.length;i++){
String getstorage= storage[i]+retval;
return storage[i]+retval;
}//for
}//storage
public static int[] find(String[] str){
for(int i=0;i!=str.length;i++){
if(str.equals (storage[i].substring(0,2))){
return indexOf(str[i], str[i].length);
else If(str[i].substring(indexOf(str[i]),str[i].length)>storage.substring(indexOf(storage[i]),storage[i].length)){
return {0,0};
};//elseif
}//if
}//for
}//find
}//StrStore

Thanks got that part fixed and I even kinda learned how to make it so that I can establish the variable somewhere else lemme show you:
public class StrStore
   private static String[] storage(String[] storage){
            for (int i=0; i!=storage.length; i++);
              String retval="";
              return storage[i] +retval;
           }//for
         }//storage
   public static String[] getStorageArray()
     String[] temp= new String[storage.length];
     for (int i=0; i!=storage.length; i++){
              temp= storage[i];
return temp;
}//for
}//getStorageArray
public static int[] find(String[] str){
for(int i=0;i!=str.length;i++){
if(str[i].equals (storage[i].substring(0,2))){
return {indexOf(str[i], str[i].length};
else if(str[i].substring(indexOf(str[i]),str[i].length>storage.substring(indexOf(storage[i]),storage[i].length)){
return {0,0};
}//elseif
}//if
}//for
}//find
public static int[] encode(String str){
for(int i=0;i!=str.length;i++){
if(str[i].length>storage[i].length);
return str[i]+storage[i];
else{
find(storage[i]);
}//elseif
}//if
}//for
}//encode
public static Int[] decode(int[] code){
for(int i=0;i!=str.length;i++){
return find(storage[i]);
}//for
}//decode
public static void main(String[] args)
int[][] codes = new int[args.length][];
for(int i=0;i!=args.length;i++){
codes[i]=encode(args[i]);
}//for
storage(getstorage);
System.out.println("storage = "+ getStorage);
for(int i=0;i!=args.length;i++){
System.out.println(decode(codes[i]));
}//for
}//main()
}//StrStore
however Im still coming up with 5 errors now one is stating that in this section:
public static String[] getStorageArray()
     String[] temp= new String[storage.length];
     for (int i=0; i!=storage.length; i++){
              temp= storage[i];
return temp;
}//for
}//getStorageArray
that a class is expected but I thought I had the class defined? I get that also here:
   public static int encode(String str){
           for(int i=0;i!=str.length;i++){
             if(str.length>storage[i].length);
return str[i]+storage[i];
else{
find(storage[i]);
}//elseif
}//if
}//for
}//encode
but instead of the beginning I get it at the very last line of that snippet
then I get that these two variables are incompatible
private static String[] storage(String[] storage){
            for (int i=0; i!=storage.length; i++);
              String retval="";
              return storage[i] +retval;
           }//for
         }//storage
