Have you decrypted and shrank the dvd first?

What do you mean use a data file, text file and the other stuff? An interface is implemented like this:

class Test implements MyStackInterface
{
    //now it must override the methods
}

Never heard of a vaw file?

If you mean raw, then it can't be much more than using an File object, FileOutputStream, BufferedReader, DataInputStream, or something along those lines.

And to you to, in 2 days :)

I turn 17 in 7 days!

Simple global constants should do.

I got 18 out of 15 right.

I think you're doing a fine job. What I don't like about this site is the community in general. What I mean by that, is the people here are not that friendly. Yes, there are a few, but for the most part they are not friendly. It just seems you are attracting the wrong kind of people. Either they're not very nice, or simply make one post which asks for their work being done, and then they're gone.

Just my opinion.

Math.pow(base, power);
Math.sqrt(x);

Where are you making a connection to the DB?

Do you mind telling us the steps you've taken? It would be easier to diagnose a problem that way.

That's part of it, but best practice extends to code written...In my opinion. For example, use methods and utility classes as much as you can, rather than re-inventing the wheel. Also, definately leave out repetitive code.

The list could go on and on, but that's just a few points.

You never know ;)
Was wondering when you'd gone for the exam though.

I haven't taken it yet. If I do, it will be a while from now. I've been studying C++ and I'm kind of rusty on the more harder subjects of java...which I hever had a good grasp on. Overall, I'd say maybe another 1.5 or two years, but still I don't think I would ready by then.

I made 91% when I took it.

You do know I'm joking, right?

Create a style with some imageicons and whatever else you need in html.

I made 91% when I took it.

Maybe it's just me, but I wouldn't "modify" anything to be static unless it's a utility class like Math, or if I really have to. I've seen a few people that say make everything static unless you don't need to, which I don't agree with. I guess a lot of people get tripped up when using the main method since it cannot reference anything but static contexts.

Have you tried using gridwidth or ipadx?

yes but it is a java problem ;)

Ummmm.....Are you trying to use the "new" construct to instantiate an abstract class????

The root cause error should give it away.

Oh, I see. I appreciate the help sunny.

Well, I knew that would work, but I'm trying to split functionality up as much as I can. Is there not a way to have this Store class as an external source code and import it into the Person class?

I've tried this:

#include <Store>

and

#include <Store.cpp>

Both of which didn't work, but they are in the same directoryl

I have a class Person and a Class Store. I didn't find any way to really inherit Store in class Person, so I created Class Store in a namespace called StoreClass.

In the person class this doesn't work:

using namespace StoreClass;

it says that namespace StoreClass is undeclared.
I also tried to include the actual File which is called Store.cpp, but it says it couldn't find that either. Both classes are in the same directory.

Is there something I'm doing wrong?

Here's an excellent article on tuning the GC:

http://java.sun.com/docs/hotspot/gc1.4.2/

I hope you are asking for this....
when you do something like this

cout<<obj;//object of class

it is equivalent to

cout.operator<<(obj);

first argument passed is implicit this pointer and second one is obj

Ok, I think I got it. Correct me if I'm wrong:

The first parameter(ostream&) is actually on the right side of the operator << and the object it's operating on is on the right side of the << operator. Is that correct?

Maybe you should test lowercase letters instead of uppercase?

Thanks guys, that really helped a lot and cleared things up. It turned out that I didn't declare it as a friend. Now, one thing I don't understand is where the ostream& is passed since it's the first argument. I understand where Person& comes in, but I don't get where the ostream& is passed in. I know WHY it's there, but not sure where it comes from. Can anyone clear that up for me?

PS: I really appreciate the help from you guys and will be awarding rep points.

Are you talking about Java?

Kathy Sierra and Bert Bates book is the best in my opinion. You read that about 2 or 3 times and you'll make at least 75 or 80.

I have the following code:

ostream Person::operator<<(ostream& out, const Person& p)
{
           out << "/n*********************************" << endl;
           out << "Name: " << Person::getName() << endl;
           out << "Age: " << Person::getAge() << endl;
           out << "Health: " << Person::getHealthLevel() << "%" << endl;
           out << "Happiness: " << Person::getHappinessLevel() << "pts" << endl;
           out << "Sleep: " << Person::getSleepLevel() << "%" << endl;
           out << "Money: " << "$" << Person::getMoneyLevel() << endl;
           out << "Posessions: " << endl;
           out << "*********************************" << endl;

           return out;
}

It looks correct to me, but I'm getting a few errors:

`Person::operator <<(ostream &, const Person &)' must take exactly one argument
new declaration `class ostream Person::operator <<(ostream &, const Person &)'
ambiguates old declaration `class ostream & Person::operator <<(ostream &, const Person &)'
In method `ostream::ostream(const ostream &)':
`ios::ios(const ios &)' is private
within this context

Is there something I'm doing wrong?

It is really ugly. The GBL is very powerful and has a neat concept to it, but it just doesn't work for my needs.....I wish it did, but it doesn't. If there was an easy way to tie it in with arrays and loops I would love it. Take a calcualtor for example. I would much rather hold ALL the buttons in an array and work from there, rather than coding everything out seperate. It's just too much code involved and it's hard to keep up with.

Normally, my approach is to use JPanels which have their own layout. In the end, I would position the JPanels using setBounds(int, int, int, int); which gives you complete control of the positioning. That saves a lot of time, because the majority of component positioning is taken care of with the jpanels, and all that's left is positioning the few jpanels that you have holding all of that.

Overall I wouldn't mind using the GBL, but it's too much cluter involved.

I take it the STL is very important? I was thinking people would lean toward Bjarne's book, but I guess I was wrong.

PS: Thanks for the link. I wish I had found it earlier(before I bought a few books of course).

Well, you can only POST a message using a POST query. Any parameters passed via a URL, create a GET query.

Now, you could use JavaScript, to create a form, a lot of invisible variables, populate those variables, then call the form's "submit()" method, which will POST the form. You can only do that on a page you "own", of course.

"AJAX" is a funny little beast - it refers to scripting the XMLHttpRequest object. It doesn't do a POST, it fires off another request, "behind the scenes", so that the user doesn't see any page refresh.

I guess AJAX was it. I remember working with the XMLHttpRequest. My first intentions was to create a form, because I have seen examples of 'dummy' forms created which do basically the same thing I was looking for. Either way I appreciate the replies.

You can always write your own renderer, but I'd guess that would be quit difficult.

Anyways, not sure I fully understand your problem.

I'm finshed with teach yourself c++ in 21 days. It's been fairly good at teaching the basics, but I have two books I need to select from to read next:

c++ programming language --bjarne stroustrup
the c++ standard template library

I just don't which to read next. Which would you guys choose?

Simply concatentate URL and ARGs. In fact, you don't even need a separate variable and/or call for "args". They are simply part of the URL.

You can do that, but that doesn't make it using a post method. This was actually a problem my friend had, and we used some kind of xml thing to do the job, because javascript alone can't make post calls. I wish I could remember the name of it. It may have been called ajax or something.

I actually prefer using the GridBagLayout. It is definantly the most powerful layout and if used correctly, can produce great looking layouts. The biggest key with any GUI layout is componitizing the whole thing. E.g.: placing like components on their own JPanel and then taking all the componitized JPanels and placing them on one larger JPanel.

The only other layout manager i use is flow layout and the only time i use it is when creating a popup windows button bar.

Regards,

Nate

It's very powerful, but the problem is, what if you have 20 components? It takes a billion lines of code with GBL, when you can simply nest layout managers, use arrays, and loop through the initialization.

how to add a menubar in an applet :rolleyes:

What's the question?

Javascript is NOT Java. Java is NOT Javascript.

I'm not sure there's an explanation for people who do such things. It's either an intentional mis-interpretation of their religion, or they just feel rejected by society....Who' knows?

What's webmaster world in vegas?

AMD executes more instructions per cycle, which means it doesn't need to be as fast as P4's.

Advanced Micro Devices all the way.

I personally have a PM which I really like. I can play any game I want with just a 1.5ghz PM processor.

Oh, Ok. I see what's happening now. You have to start the first loop at zero, and end at a value one less than the size, and for the inner loop start at 1, end at zero. However, I would have never caught that without you guys.
Thanks for all the help!

Dragon, thanks for showing a better alogorithm, and rash, thanks for such a detailed explanation of what I was doing wrong.

I am way sexier then all of u put toghether lol!

beat that!

I am way sexier than all of you put together.

beat that.

I can't seem to get this sorting alogorithm to work:

#include <iostream>


void sortAssending(int nums[], int size);

int main()
{
    int nums[] = {175,167,160,164,183,187,188,179,176,175,
                  169,175,176,178,165,160,173,165,187,178};
    sortAssending(nums, 20);
    for (int i=0; i<20; i++)
    {
        std::cout << nums[i] << std::endl;
    }
    
    system("PAUSE");
}

void sortAssending(int nums[], int size)
{
     for (int start=0; start<size; start++)
     {
         for (int end=size-1; end>=0; end--)
         {
             if (nums[start] > nums[end])
             {
                 int temp = nums[start];
                 nums[start] = nums[end];
                 nums[end] = temp;
             }
         }
     }
}

It seems to do everything right except the very last number is not in place. Can anyone spot the problem?

Process p = Runtime.getRuntime().exec("path/programname");

Shouldn't be any different than writting something in a different language. If you are writting an online app, then java's probably the way to go. If you're worried about speed, then you shouldn't be. Since Java 1.4, it uses the Hotspot VM by default, which does pretty much the same as the .Net engine. The .Net engine simply compiles modules as it loads them. Hotspot compiles code that is frequently used only, thereby saving loads of memory and reducing startup time.

When someone reffers you to this site.

String s = "lowercase";
String s2 = s.toUpperCase();

Remembers Strings are immutable so this won't work:
String s = "lowercase";
s.toUpperCase();

HI ,

can anyone tell me how i can edit rotation in my xsl?

my xml lookes something like that:
<root>
<obj col="0xff0000" xPos="25" yPos="0" widht="2" height="2" angle="30" />
</root>

my question is how can i write the angle in the xsl?

thanks

Not the right forum to ask these questions.

If someone could help me doing a code in VB to do the following:

The output should be a list of all posible ways in which (m) different Males
and (f) different female could be line up if no two females could be together
(one female can not stand after another female in the line).

Thanks for any suggestions,

EMG

Would you like me to write the whole thing for you?

Use saverbeans.
