Why do we use "super" for some methods?
What I have noticed is that in some methods we have
- (void)dealloc {
[label release];
[message release];
[super dealloc];
where at the end of the method we have [super dealloc]
Why do we have that?
The parent class may have allocated resources that you don't know about. Once you're finished deallocating resources in your object, you call the super-class' (parent-class') dealloc method to deallocate the things that it allocated. If you don't, whatever it allocated won't be deallocated.

Need help!! How to use super in equals() method and makeCopy() method?
This is my Name class:
class Name {
private String title;
private String name;
public Name(){
title=" ";
name=" ";
public Name(String title){
setTitle(title);
name=" ";
public Name(String title,String name){
setTitle(title);
setName(name);
public void setTitle(String title){
this.title=title;
public String getTitle(){
return title;
public void setName(String name){
this.name=name;
public String getName(){
return name;
} This is my Person Class
class Person extends Name{
private String address;
private String tel;
private String email;
public Person(){
super();
address=" ";
tel=" ";
email=" ";
public Person(String name){
super(name);
address=" ";
tel=" ";
email=" ";
public Person(String title,String name,String addressStr){
super(title,name);
setAddress(addressStr);
tel=" ";
email=" ";
public Person(String title,String name,String addressStr,String phoneNum){
super(title,name);
setAddress(addressStr);
setTel(phoneNum);
email=" ";
public Person(String title,String name,String addressStr,String phoneNum,String emailStr){
super(title,name);
setAddress(addressStr);
setTel(phoneNum);
setEmail(emailStr);
public void setAddress(String add){
address=add;
public String getAddress(){
return address;
public void setTel(String telephone){
tel=telephone;
public String getTel(){
return tel;
public void setEmail(String emailAdd){
email=emailAdd;
public String getEmail(){
return email;
public boolean equals(Person inputRecords){
boolean equalOrNot=false;
if(inputRecords.super(getTitle()).equals(title)) //this is wrong
if(inputRecords.super(getName()).equals(name)) //this is wrong
if(inputRecords.getAddress().equals(address))
if(inputRecords.getTel().equals(tel))
if(inputRecords.getEmail().equals(email))
equalOrNot=true;
return equalOrNot;
public void makeCopy(Person copyInto){
copyInto.super(setTitle(title)); //this is wrong
copyInto.super(setName(name)); //this is wrong
copyInto.setAddress(address);
copyInto.setTel(tel);
copyInto.setEmail(email);
}How can I correct the wrong part?
I don't understand how to use super in equals() method and makeCopy() method.Try something like this ...
public boolean equals(Object other) {
if (other==null || !(other instanceof Person)) return false;
Person that = (Person) other;
return getTitle().equals(that.getTitle())
&& getName().equals(that.getName())
&& getAddress().equals(that.getAddress())
&& getTel().equals(that.getTel())
&& getEmail().equals(that.getEmail())
Notes:
* This overrides Object's public boolean equals(Object other), which is (probably) what you meant.
* You don't need to call "super.getWhatever" explicitly... just call "getWhatever" and let java workout where it's defined... this is better because if you then override getTitle() for example you don't need to change your equals method (which you would otherwise probably forget to do, which would probably have some interesting side effects.

[SOLVED] Getting freezes after using dwm for some time and exiting it
Hello, I have an Asus Ux51, with a fresh (less than a month) arch installation. If I recall correctly I had a couple of freezes in other occasions but I don't remember much about those so I rather focus on the only freeze I can more or less reproduce and I've been having lately. After using dwm for some time with a couple of programs opened (rTorrent, browser, and some terminals for instance), if I close dwm or just press the power button to shut down, it starts closing everything and either stays with a black screen, or hangs while X prints the log information. It's not always though, for example, if I just boot it, open dwm and close it without giving it much use it usually closes fine.
Tried googling a bit to see the usual ways to troubleshoot this but didn't get really far.

Found this recent thread in the forums, I'll give REISUB a try late, but the times it freezed I remember trying to blindly reboot it, or switching off virtual console and couldn't.
In case it's of any use, this is my # uname -a
Linux arch 3.10.3-1-ARCH #1 SMP PREEMPT Fri Jul 26 11:26:59 CEST 2013 x86_64 GNU/Linux
Could it have something to do with the nvidia optimus setup that this laptop has? When installing arch I found out that there was no support yet for it so I'm just using the intel drivers (following what the arch wiki said).
Any ideas or advice to point me in the right direction would be very much appreciated.
Thanks in advance.
Last edited by contiver (2013-08-16 20:25:34)I don't start st in my .xinitrc. I launch it from dmenu and usually everything is fine. If I launch it from dwm's internal command using Alt-Shf-Return, X freezes 100% of the time. A workaround was suggested by st's main developer to call st like this:
static const char *termcmd[] = { "/bin/sh", "-c", "st", NULL };
but it didn't work for me.
Very rarely X will freeze anyway. I haven't been able to pin it down. When X fails, my journal returns this:

I do not have an Apple computer, I have had Itunes previously but had not used it for some time, I have Itunes gift cards but can not get ,on to use them. I have tried to download Itunes again but the following keeps poping up, "The Itunes library is locked on a locked disc, oryou do not have write permission for this file." How can I overcome this?
To solve this issue all I did was check to ensure that the file permissions were set as described by the earlier posts, followed by simply deleting the iTunes Library Genius.itdb file. Once the file was deleted I was able to open iTunes without difficulty. Note that I am running Windows 8. Hope this helps!

Why do we use dunning for vendors
Hi All...
We create dunning for customer to send them reminders for payment....But why do we use dunning for vendors (in Vendor Master Data)??
Txk,
UmeshHi,
If you dun customers who are also vendors and want to clear the items, the dunning program lists both the overdue customer items and the overdue vendor items in the dunning proposal, and determines a joint balance.When you dun a customer who is also a vendor, only the master record information of the customer is relevant.The items can only be cleared if the same dunning procedure has been defined in the standard dunning area for both customer and vendor.
Hope this helps you. let me know if you need anyother information.

Why should we use WSDL for developing webservices
I need to develop Webservice Application for our Client .
I dont know anything about WSDL4J
Hi from the net i found this
"The Web Services Description Language for Java Toolkit (WSDL4J) allows the creation, representation, and manipulation of WSDL documents.
Is the reference implementation for JSR110 'JWSDL' (jcp.org)."
But anybody please tell me why should we use WSDL for developing webservices ??
Is there any specific advantage we will get ??
And Can body please point me a link where to start for working with WSDL4j ?
Thank you very muchi seriously doubt you want to use wsdl4j unless you are doing really advanced webservice work. assuming you are developing this webservice from scratch, you basically want to use JAXWS: define an appropriate interface and your value classes, and let JAXWS do the rest. metro is the JAXWS implementation included in the oracle jdk and it has great tutorials and reference documentation online. i'd suggest you start here: http://metro.java.net/getting-started/

Where-used list for view methods, and context elements
I want to know where a context element in the component controller is used (and if I can delete it).
Is there something like a where-used list for a context element?
Similar question:
Is there a where-used list for a method of a view?
Best regards,
DanielHi Daniel,
Its not supported for both of these..

Why do we use super when there is no superclass?
Hello,
I have a question about the word "super " and the constructor. I have read about super and the constructor but there is somethong that I do not understand.
In the example that I am studying there is a constructor calles " public MultiListener()" and there you can see " super" to use a constructor from a superclass. But there is no superclass. Why does super mean here?

Isn't that simplier to use the constructor instead of using "super"? I mean using the constructor jpanel () ?

You can't call the super class constructor directly if you are trying to construct the sub-class. When you call it directly it will construct an instance of the super class but that instance will NOT be an integral part of the 'MultiListener' sub class you are trying to create.
So since 'MultiListener' extends JPanel if you call the JPanel constructor directly (not using super) your code constructing a new instance of JPanel but that instance will not be an ancestor of your class that extends JPanel. In fact that constructor call will not execute until AFTER the default call to 'super' that will be made without you even knowing it.
A 'super' call is ALWAYS made to the super class even if your code doesn't have an explicit call. If your code did not include the line:
super(new GridBagLayout()); Java would automatically call the public default super class constructor just as if you had written:
super();If the sub class cannot access a constructor in the super class (e.g. the super class constructor is 'private') your code won't compile. -
Trying to use super class's methods from an anonymous inner class
Hi all,
I have one class with some methods, and a second class which inherits from the first. The second class contains a method which starts up a thread, which is an anonymous inner class. Inside this inner class, I want to call a method from my first class. How can I do this?
If I just call the method, it will use the second class's version of the method. However, if I use "super," it will try to find that method in the Thread class (it's own super class) and complain.
Any suggestions?
Code:
public class TopClass
public void doSomething(){
// do something
=============================
public class LowerClass extends TopClass
// overrides TopClass's doSomething.
public void doSomething(){
// do something
public void testThread(){
Thread t = new Thread(){
public void run(){
doSomething(); //fine
super.doSomething(); //WRONG: searches class Thread for doSomething...
t.start();
}Classes frequently call the un-overridden versions of methods from their superclasses. That's that the super keyword is for, if I'm not mistaken.You're not mistaken about the keyword, but you're not calling the superclass method from a subclass. Your anonymous inner class is not a subtype of TopLevel. It's a subtype of Thread.
Here it is no different, except that I happen to be in a thread at the time.It's vastly different, since you're attempting to call the method from an unrelated class; i.e., Thread.
I could also be in a button's action listener, for example. It seems natural to me that if I can do it in a method, I should be able to do it within an anonymous inner class which is inside a method.If you were in an button's action listener and needed to call a superclass' implementation of a method overridden in the button, I'd have the same questions about your design. It seems smelly to me.

SMS works well and is generally free for most plans here. I'd like to be able to send messages via SMS from my iPhone for many of these contacts because something changed in IOS 8 iMessage and now iMessages seem to get lost. Plus as before they can end up in multiple threads. This latter issue seems to be worse as well with iOS8 but not sure why.
For example one friend set up an iPad with her apple ID and subsequently gave it to her son. She also has an iPhone. I've been exchanging iMessage/SMS's with her which worked fine until the upgrade. Then she stopped getting my messages on her iPhone. Turns out that they were landing on the iPad. While it may be that she doesn't have things sorted correctly on her iPhone that doesn't change the fact that prior to iOS8 she could get my messages. So I'd like to designate her and a number of other contacts as SMS only.
Additionally I am seeing more multiple threads from the same contacts. Not sure why but it seems to have something to do with iOS 8 sucking in additional email addresses, e.g. @icloud.com and subsequently using these in some messages even though the contact is the same person. I've tried adding the new email address into the contact card I have on file for that person and this simply resulted in two threads with the same contact name.
Really what is up with this and why does Messages need to keep track of all this info? The only requirement to direct a message between to iDevices should be valid Apple ID's on both with a means to reference this (Phone Number, Apple ID Email Address) in the respective contact. In the absence of this the message should be sent as SMS.I have the same problem on iOS 7.0.3. With one particular friend I receive iMessages from her just fine and I can send her iMessages from Mac OS X and Messages on iPad, but Messages on my iPhone keep sending her my messages as Text messages. I send iMessages just fine from the same iPhone. SFChuch, what ios version is your recipient using? Did they sign up on iCloud? I wonder if the problem happens with recipients who are not properly registered on iCloud or some special case like that.

Can't use image as link using asfunction for some reason
I have a pretty large which was coded using AS2 in about 2006 so I'm trying to make a few changes using AS2 which I'm pretty rusty on. I have a swf which loads an xml file into a textarea in flash and it all works well. I have to link some images which appear in the xml file but those images have to be links to external sites and that is where I am running into problems with my asfunction. Here is the code.
Function in my AS:
function launchSite(arg) {
if(arg == "agri") {
getURL("http://www.usda.gov/wps/portal/usdahome", "_blank");
then of course arg will take different values for the other links:
In the xml file, here is the asfunction code:
<a href='asfunction:_root.launchSite,agri'><img src="images/agri.gif"></a>
What is happening is the function is working and the external link is opening in a new browser window, but the xml stops at that point so most of the agri.gif image and the rest of the page are gone. If I change the img tag to just a text link, then all is well .. but my client wants the images to be the link.
To further complicate, if I remove the link text and have only the img tag, the page is fine. They just won't work together for some reason. Any thoughts?
Thanks!
Nancy>the cdata tag is needed so you can load the xml that contains html tags.
Interesting since my xml files are full of html tags and everything else renders just fine without CDATA tags. My textarea is configured to allow HTML.
AS as follows:
//set up the textarea
//init TextArea component
myText.html = true;
myText.wordWrap = true;
myText.multiline = true;
myText.label.condenseWhite=true;
//set up the XML
myXML = new XML();
myXML.ignoreWhite = true;
myXML.load("xml/acts.xml");
myXML.onLoad = function(success)
var myArray:Array = myXML.firstChild.childNodes;
myTitle.text = myXML.firstChild.attributes.title
myLoader.contentPath = myXML.firstChild.nextSibling.attributes.src
myText.text = myXML.firstChild.nextSibling.nextSibling
function loadFunction(target){
myXML.load(target);
myXML.onLoad = function(success)
var myArray:Array = myXML.firstChild.childNodes;
myTitle.text = myXML.firstChild.attributes.title
myLoader.contentPath = myXML.firstChild.nextSibling.attributes.src
myText.text = myXML.firstChild.nextSibling.nextSibling
//function to load the external XML
function launchSite(arg) {
if(arg == "agri") {
getURL("http://www.usda.gov/wps/portal/usdahome", "_blank");
pertinent part of the xml as follows (portion of the text node which displays all the text):
<a href='asfunction:_root.launchSite,agri'><![CDATA[<img src="images/agriculture.gif">]]></a> Department of Agriculture: The Department of Agriculture began in 1862. The main job of this department is to keep our food is safe and healthy. They also work with farmers if they need help selling their crops both in the US and around the world. Secretary of Agriculture is Mr. Thomas J. Vilsack.
I added the CDATA tags at your suggestion. What that gives me in the browser is a working function (loads the external site in a new window as desired) but instead of the image, I have the img tag printed out due to the CDATA tags (which by definition is not parsed).
I have had pages on pages like this in this site since 2006 (which is why it's done in AS2 and not 3) and have never had a problem until the client wanted the images to be links to the external sites. If I put in the image tag without the link, it works. If I put in the link tag with a text link rather than the image, it works. It's the two together that do not work.
Does that make sense?
Thanks again!
Nancy
after that you need to parse the xml correctly and assign to your textarea. are you? -
