Does it really true that Epson tx110 don't have refill ink?
Because when i'm trying to find a refill ink, the seller says that there was no refill ink for epson tx110.
Anyway, what is a continuous ink supply system?

you can conserve  black ink by telling the printer to use other colours to mix in the black.
Any picture that uses a lot of dark colours consumes a lot of ink, printing pictures is always taxing on ink.

using other colors to mix in black is pretty interesting.
oh, dark colors consumes a lot of ink, i better watch out about that.
thanks a lot.

Yehey! the program now works perfectly.
Thank you very much everyone that helped me.
thanks a lot.

Now this program is finished.
but, can i ask some last question. Please.  :)
I need this so that i can explain it to my professor when she ask me.
Why should I declare variable "i" as string? String i = "-0"; Is it so that java will read "-0" different form a "0".
Why should i declare variable "x" like this: int x=Integer.parseInt(i);? Is it to convert the string variable i to an integer?


thnaks a lot.

i've change it to:

    public static void main(String[] args) {
String i = "-0";
if(i[0]=="-"&&i[1]=="0")
{System.out.println("INVALID");}
else

if (x>0)
{System.out.println("POSITIVE");}

i dunno why it don't run.

Byakko said, August 25, 2009, 01:09:47 pm
-0 is most likely simplified to 0 as soon as you put it as a number, because -0 = 0. Like, if you declare a number (integer, double or whatever), even if you set it to "-0", if you try to display it immediately afterward it will still give you 0 and not -0.
Declare it as a string right off the bat and test for -0 then you can make it a number, I don't even reckon the number made tostring will give you the minus back.
You can check by writing i = -0 and then putting a sysout to display it, it will give you 0. Not +0, not -0, just 0.
Yes you're right.
it gives me only 0.  ???

anyway, here's what i used to do:

[mcode]class Switch {
    public static void main(String[] args) {
double i = -0;
if (i>0)
{System.out.println("POSITIVE");}
else
    if (i<0)
    {System.out.println("NEGATIVE");}
    else
        if (i==+0)
        {System.out.println("ZERO");}
        else
            if (i==-0.0)
            {System.out.println("INVALID");}
            else
                {System.out.println("INVALID");}
    }
}

still doesn't work.

Hi i need help.
Our professor gave an assignment i thought is easy, but not.
its about Java programming language with the usage of Net beans 5.0.
its the usage of IF_ELSE.
the output is when you input a number, it will determine if the inputted number is positive(greater than 0), negative(lesser than 0), Zero(0) or invalid(if inputted is -0).
everything is alright but still have a problem,when i inputted "-0" it displays "0" instead of "invalid".
What should I do?

i'm trying to make everything alright for almost 3 hrs but i failed.
can anyone help me out please.
thanks in advance.

Now I really understand the queuing.
Thanks a lot iced.
I also understand a bit about scheduling but i don't know where this apply.
It schedules processes run right?
what are processes? if processes are programs?
how do scheduling vary in it?

thanks a lot for help and sorry for my lots of question.  ;D

I have a question related in computing. Because I have a report and I really need help.
I can't simply understand these definition I have found.
FIRST:
Scheduling is a key concept in computer multitasking and multiprocessing operating system design, and in real-time operating system design. In modern operating systems, there are typically many more processes running than there are CPUs available to run them. Scheduling refers to the way processes are assigned to run on the available CPUs. This assignment is carried out by software known as a scheduler.

What? and How? is Scheduling?
What are scheduler? are anti virus softwares are scheduler?

SECOND:
queuing refers to lining up jobs for a computer or device.

What is queing? I just know about downloading but i can't understand queing?


Please, anyone, i really need help and examples to understand them.
