Contrast �waterfall� development and iterative development

could anyone tell me how to contrast �waterfall� development and iterative development??
Thx

Waterfall development means spending an afternoon in a Hawaiian waterfall with a bikini-clad native.
No matter what your professor tells you, real professionals like me prefer this method. The books are trying to discourage you from it because they want to keep those natives to themselves.

Reverse Strings using rercursion and iteration

Hi,
I really need some help, am quite new to java and am struggling.
I want to design 2 methods, both 2 reverse strings.
1) uses StringBuffer and iteration
2) uses Strings and recursion
I would be greatful for any advice or help.
Thanx xxxxx Nats xxxxxx

Oh, you need to do it using both methods.... Sorry, didn't realise it was coursework :)
Using StringBuffer and iteration
public StringBuffer reverse(StringBuffer buff) {
    int halfLen = buff.length();
    int len = buff.length();
    for(int i=0; i < halfLen; i++) {
         char c1 = buff.getCharAt(i);
         char c2 = buff.getCharAt((len - i) - 1);
         buff = buff.setCharAt(i, c2);
         buff = buff.setCharAt((len - i) - 1, c1);
    return buff;
}And for String using recursion
public String reverse(String str) {
    char[] chars = new char[str.length];
    str.getChars(0, chars, 0, str.length());
    reverseChars(chars, 0, str.length() / 2);
    return new String(chars);
private reverseChars(char[] chars, int index, int halfLen) {
    //* end condition
    if(index >= halfLen) return;
    topIndex = (chars.length - 1) - index;
    char tmp = chars[index];
    chars[index] = chars[topIndex];
    chars[topIndex] = tmp;
    reverseChars(chars, ++index, halfLen);
}I only wrote this code on the fly so things may break but it is a start.

What does salt and Iteration mean

What does salt and iteration mean in the constructor of PBEKeySpec

A key is generated from your PBE password using MD5 hashing.
To make it more difficult to attack
1) the hash is initialised with a 'salt' value before hashing the password,
2) the result of first hashing is hashed iteratively the number of times given by the 'iteration' count parameter with the final hash value being used as the key.

A/B Color contrast in develop module

It would be really nice to hace a slider (or three, I'll explain) for "color contrast".
Threre is "contrast" slider that influences the luminosity basically. What I would want to have is a way to control color contrast while preserving luminosity as well as preserve color balance.
A single slider implementation
Basically the simplest way (but a bit crude) to do it would be with a single slider.
The slider defaults to 0.
Moving it to the right would be equivalent to the following photoshop procedure:
Change mode to LAB
Curve adjustment
Steepen both the A and B curves linearly (pull extreme points in and leave the curve straight, plus keep the center where it is to preserve color balance)
Leave the L curve alone
Apply
switch mode back to RGB
Moving it left would be the same, except the AB curves would be made shallower rather than steeper (rotate the curve clockwise instead of counter clockwise about the center)
A two slider implementation
Same as the above, except that you would have separate A and B sliders (you might call the tint contrast and temp contrast to be consistent with the color balance sliders, which are just like moving the center point of the AB curves)
A three slider implementation
Basically this is like having bothe the one slider ("overall color contrast") and the two sliders ("temperature contrast" and "tint contrast"). It's a bit redundant but having the single control there makes it easier when you simply want to globally increase the color contrast without being too picky about the two separate controls (I guess easier for beginners)

Not at all. The saturation control has quite a different effect that this, and much les subtle. Saturation just increases saturation without changing the hue. This actually changes the hue causing a separation in hues that is impossible to achive in any manuver you would to in RGB space. It drives colors apart rather than increasing their chroma.
Try it yourself on a few images (especially on images that have nearly uniform color, such as deserts or faces. You will see that this is an entirelty different thing than saturation.

The difference in sharpness and overall contrast between LR5 and LR4 low res. export JPEGs

Installed the evaluation copy of the LR yesterday and as always compared with the previous version (4.4) of the program. The first and not very pleasant difference was the sharpness of the exported JPEGs in low resolution. In full resolution exports it is not that much noticeable. As you may see on the below photo LR4 export is noticeably sharper than LR5. All the export settings were the same in both versions. I used my saved export preset for both JPEGs. The LR5 exported JPEG is slightly lighter than the one in LR4.4. Both photos look the same in develop mode screen, so the difference is in export processing.
Would be great to know hear the experience, thoughts and comments of others about it.

I also hope that it'll be fixed soon.
Yeah, all other bugs in Lr5 I've been able to find acceptable workarounds for, but I'm not sure what to do about this one for the mean time - any ideas?
If no acceptable workaround can be found, then +1 vote: 5.0.1 in a hurry.

How to pick max value from a column of a table using cursor and iteration

Hello Everybody
I have a table loan_detail
and a column in it loan_amount
now i want to pick values from this table using cursor and then by using iteration i want to pick max value from it using that cursor
here is my table
LOAN_AMOUNT
100
200
300
400
500
5600
700i was able to do it using simple loop concepts but when i was trying to do this by using cursor i was not able to do it .

Why when i convert to black and white and change, contrast, exposure etc and get it right in preview i open it and its brighter and looks different to the preview?

The images also look different in preview and when i upload them to adobe Revel but when i put them back in photoshop they look Ok.

I convert, in raw to black and white and add sharpness and clarity theirs and a few other options Temp etc if need be. Then i open them into photo shop as black and white. There i place around with the exposure setting but as you do it you have the preview button clicked so you see what the finished photo will look like. When i hit change normally the photo changes and looks like it was in the preview.But now with out changing any settings in photoshop, as i change the photo the preview is different when i click ok to make the changes. This comes and goes in photoshop and its getting a bit frustrating as i do a lot of black and white photos and have been doing for years but i am having this problem over the last 6 months.
No i haven't changed colour settings i have photoshop on the preset settings.
'Preview" when you are changing contrast etc their is the preview option so it shows in photoshop what the changes will be. But what i see when i am changing it is different when i open it. make be a point brighter or not as contrasty as i see it as i am changing the settings.

TableView and iterator

I have a check box that was added thru iterator.
How do you stay in the same page of the tableview after clicking a check box?
Example.
there are 4 pages with 5 rows each. If i checked a box in page 4, it always goes to page 1.

What you can do is create a button and make the user click on the button..
Then the onClick Event of the button, use the code to read value..!
Hope this helps.

Low contrast of text and outlining

Hello,
Choice of colors in the discussions makes it very difficult to read. When you first time go to the discussions page it just strikes your eyes very hard with low contrast text. It takes some time to get used to it. And then, after the ten minutes of reading eyes are exploding because of the constant pressure in trying to focus your vision.
Outlining of the messages to different horizontal levels is actually confusing in my opinion. However, it might be just personal feeling.
But, the colors! Common guys, current "pastel" theme will drive most of the people blind or out of this website.
Best

I find the paler color in the list of posts hard to read, too, with my "experienced" eyes.

Get Binding and Iterator from UIComponent

I have a pageTemplate with a reusable menu which contains: navigation buttons (previous, next, ... records), commit and rollback operations, and create/Delete Record.
My pages could contain components which have more than one IteratorBinding, for example a couple of tables master/detail.
My first idea was this:
I have to add for each BindingIterator, all record actions with the same pattern name: <operationName><IteratorName>, then I could execute the correct operation in the actionListener for each button with a simple search on the pageTemplateBean.
    public void onFirstClicked(ActionEvent actionEvent) {
        BindingContext bctx = BindingContext.getCurrent();
        DCBindingContainer bindings = (DCBindingContainer)bctx.getCurrentBindingsEntry();
        String iteratorName = (String) JSFUtils.resolveExpression("#{viewScope.focusComponentIteratorName}");
        String operationName = "First"+iteratorName;
        OperationBinding oper = (OperationBinding)bindings.get(operationName);
        oper.execute();
For this, I have to Know which is the last UIComponent which had the focus and get its Binding Iterator.
I have added a ClientListener and ServerListener programmatically for get the UIComponent which has the focus in each moment. (pageLoad with f:event JSF2).
JavaScript code in PageTemplate:
<af:resource type="javascript">
      function clientFocusMethodCall(event) {
          component = event.getSource();
          AdfCustomEvent.queue(component, "focusComponentEvent", null, true);
          event.cancel();
    </af:resource>
Create ClientListener and ServerListener programmatically:
    private void addFocusListenerComponent(UIComponent c) {
        ClientListenerSet cls = new ClientListenerSet();
        cls.addListener("focus","clientFocusMethodCall");
        cls.addCustomServerListener("focusComponentEvent", JSFUtils.getClientMethodExpression("#{pageFragmentTemplateBean.handleFocusComponentRequest}"));
        //----------------------- INPUT --------------------
        if (c instanceof RichInputText) {
            RichInputText it = (RichInputText)c;
            it.setClientComponent(true);
            it.setClientListeners(cls);
        } else if(c instanceof RichSelectOneChoice) {
            RichSelectOneChoice it = (RichSelectOneChoice)c;
            it.setClientComponent(true);
            it.setClientListeners(cls);
After that, I have this Event, which is launched after every focus event.
public void handleFocusComponentRequest(ClientEvent event){
        System.out.println("handleFocusComponentRequest "+event.getComponent().getClientId());
        System.out.println("---"+event.getParameters().get("payload"));
        UIComponent c = event.getComponent();
The next step is get the AttributeBinding and IteratorBinding and save them in ViewScope variables, but I dont Know how get it.
PS: Commit and Rollback operations are easier since the are common to the ApplicationModule.
jdeveloper 12c, 12.1.2.0.0

Hi Frank.
I had found the second strategy but I didn't know how can update references at runtime.
My application has a MDI Desktop, in that I could have few programs opened at same time.
Each programa had a unique menu with the navigation and record operations buttons.
Now I will explain my issue with and example:
In a region, rendered a PageFragment where is showing a Master Detail tables. For this I'll have exposed a Previous Record operation for the Master and the Detail (and the others buttons too).
When a inputText from Master take the focus, the "previous" button have to reference to the Previous Operatiron of Master Iterator. Same situation when focus is in a inputText of detail Iterator.
Then the previous button have to dynamically change the operation reference after each focus action.
I think I am really close to the resolution, but I dont Know how can I get the Iterator binding for each UIComponent rendered in the page.
Thanks in advance.

ADF CreateInsert and Iterator refresh control

Hi
JDEV Version : 11.1.1.6
I have a scenario where i have dragged and dropped updatable EMPLOYEESVIEW as a form on my page with fields EMP_ID (Invisible on JSPX page)and EMP_NAME.
and have buttons called ADD EMPLOYEE and SAVE.
I enter the Value to EMP_NAME input Text box and Click on "ADD EMPLOYEE" button
On click of ADD EMPLOYEE button i m Setting the value of EMP_ID through java method and invoking createInsert Operation like this.
And i Have set Immediate property of CreateInsert button as True also "ADD EMPLOYEE" button has immediate Property set to true, since i want to show User entered EMP_NAME text on the screen bcos i need to give use an option to Edit.
            BindingContainer bindings =
                BindingContext.getCurrent().getCurrentBindingsEntry();
BindingContext bctxtree = BindingContext.getCurrent();
              BindingContainer bindingtree = bctxtree.getCurrentBindingsEntry();
              List attributelisttree = (List)bindingtree.getAttributeBindings();
              Iterator itrtree = attributelisttree.iterator();
                             while (itrtree.hasNext()) {
                                     AttributeBinding attrbind = (AttributeBinding)itrtree.next();
                   String label = attrbind.getName();
                                     System.out.println("lable"+label);
                   if(label.equalsIgnoreCase("EMP_ID")) {
                                       Boolean flag =
                          attrbind.processNewInputValue(variable);
                       attrbind.setInputValue(empid);
                       fetchVal=(Object)attrbind.getInputValue();
                        System.out.println(""+fetchVal);
here i m invoking the Operation CreateInsert and Though I would have inserted the value of EMP_ID programmatically as soon as i click on CreaetInsert/ Invoke CreateInsert Operation the Binding EMP_ID becomes Empty.
Because of which when i say "Commit" It throws me an error saying "Null cannot be inserted into EMP_ID since its primary Key"
How to retain the Value of EMP_ID binding?
Is it anything to do with the refresh condition which i m suppose to set for EMPLOYESSVIEWITERATOR????

How to handle this?

HashSet and iterator

Hi all,
I'm not new to java but i'm not able to solve the following issue:
I have a class
public class Localizzazioni implements java.io.Serializable {
private <complexType> id;
public getId().......
public setId().....
The complexType is a class defined in the code somewhere.
now i want to access it in another class i have
Set localizzazioni = new HashSet(0);
localizzazioni=opere.getOiLocalizzazioneOperas(); -- this object give an object of tyoe HashSet
for(Object object : localizzazioni) {
object.get......... // i cannot use any method defined in the class Localizzazioni
Why i cannot write inside the for
object.getId() and using it??
in other word how i can access the element containted in the object?? the object is an iterator of type Localizzazioni . The class Localizzazioni has some method but i cannot use them? why
Thanks really much
Francesco

Set localizzazioni = new HashSet(0);
I wonder why your IDE does not point you to the cause by marking this line.
At this line you declare the set to contain Objects since it is declared as "raw type".
The solution depends if you use java version 1.5 or higer of som ancient java version before 1.5.
With an actual java you should add type specification (aka generics) to the variable declaration:
Set<Localizzazioni> localizzazioni = new HashSet<>(0); // Java 1.7
with an prior 1.5 Java you need to (up-) cast your iterator variable:
((Localizzazioni)object.get()).methodOnLocalizzazioni();

Instanceof and Iterator

Hi,
Is this statement valid?
Iterator itemIt;
public boolean hasMoreItems() {
return itemIt instanceof Image ? hasMoreImage((Iterator<Image>)itemIt) : hasMore(itemIt);
}As you can see - I want to check the type of the iterator and then decide which method should be used...
And please - No statements like "try it by yourself"...
regards,
Olek
