ok, now i'm no n00b, so i checked the ram and harddrive space. there is more than enough memory (1gb total and only about 300mb used) and harddrive (can't remember exactly, but it was more than 10gb...

thanks. sorry about being out of topic, that's why i added the bit about resultset and arrays so it would seem less out of place. :)

also doesn't look like many people roam the sql threads and i...

ok, i have to get two mysql tables to work as one. one is called sale_mast_data and the other is called sale_mast_data_h. they both have the same columns. the only difference is that the one with the...

does your error message look something like the picture of the error i get? that's what i've been getting on two different computers. i'm upgrading from xp home sp2 to xp pro. i've tried 2 different...

StringTokenizer allows you to take a string and break it up into "tokens".

eg:

if you have this string:


String str = "i+have+a+banana+in+my+wallet"

i'm trying to run your code in my head (i'm not at my pc), but i'm in weekend mode, so it's not working. :)

if you check the apis for String, you see there's a method that will convert a normal...

crud, i must have edited this twice and posted replies 6 times to this thread. my opera mini is full of crap these days. maybe it's just because i'm using an ericsson?

ahh yes, the group thing. found it on that mysql query browser too.

thanks. i'll go sit in the corner and wear my n00b hat.

i have a small app that reads a forecourt program's database. i want to get the current shift's info from that and display/print it out.

ok, check your grad students file. does it have anything in it?

your code, including comments on the problem area (by me):


import java.io.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.util.*;

that message seems to be coming from your catching of the end of file exception. did you tell the FileOutputStream you want to append to the end of the end?

can you upload your code as you have it...

ummm... nope. sorry. :) i've just been assuming the indents go all funny when he posts it.

yes, if you fix the getHundreds method to what i posted, then you will get the right number.

do you still have the "public static void main" at the end? it usually pops up with that error when you're trying to run a class that doesn't have the main method in it.

ok. you haven't told the program you are going to use all those variables that you have in there. you need to start off by listing your variables:


import java.util.Scanner; // scanner for input...

what does the code look like now? you're not running only the code i stuck up did you? sorry, bad explanation i gave. :)

you should use your StudentRead class, but then just take out the...

all you need to do to test the methods, is to ask the user to give you a number, then you write that number out in words, but without saying thousands or hundreds. just tell the user he entered "one...

ok, and the problem with the closing of the program lies in the actionPerformed method:

you tell it to read from gradStudentInStream and set the text fields to what you have read, then directly...

oh, you also still need to catch an IOException in StudentRead.

and you're not writing an id to the file for GraduateStudentsButton.

!!problem found!!

when you create a FileOutputStream, you must use the constructor that has the "append" boolean in it (check the java docs). i was making the same n00b mistake two weeks ago....

i think i'm following:

when you click the button, you read a line from the file and stick the student's details in the textfields. when you've reached the last student and you click the button...

are the distances saved in a string array as well, or are they entered as strings by the user? to convert a string to an integer so that you can add and subtract etc, you should take a look at the...

not quite, good point you made there. also good that you made me remember which one does what. ;)

so mrjoli, how's the project going? also, remember to put your return statement at the end of the...

a simple method:


public int getNumber()
{
int a = 10;
int b = 2;
int c = a * b;

return c;

yes, i remembered that bit, but couldn't remember which way around it worked.

but in his program, he says:
[code]
day = --day;
[\code]
where it would be the same as:
[code]
day--;
[\code]

what exactly is happening there? i did notice that i didn't see a return in your code there.

also (this won't change the way the program functions), instead of saying "day = --day", you can say...

i imagine he wants to get a list of all the processes running, like task manager?

ok, you can worry about the caps when the program works. for now see if you can write out "one two three four".

when you have that, work at get the last two digits to thiry four. that's when...

ok, what you need to do, is to split them up. keep the main method in Payrollprogram and then everything to do with the details of a client, you keep in a different class.

to then access the...

oh, and when you use the "case" thing and your number is a double digit, then the last option would be "default".

check the example here:
...

instead of doing an if...else thing, perhaps a "switch" will be better?


private String getNumber( int i )
{
switch ( i )
{
case 0 : return "zero";
case 1 : return...

nevermind, i figured it out.

solution:

instead of creating the streams to the file in the constructor, i now create the streams in the methods when they're called and as soon as i am done, i...

i don't know how to explain it in the title, but this is what happens:

at startup, you get to the loading screen(windows xp pro with the three moving blocks). as soon as that's done, you get the...

i don't think that would work. java is going to have a hernia about you trying to use "System.out.print("ans" + mulTest());". mulTest() is a void method, and the wayyou are using it there is as if it...

if you get that error, and it mentions that "savscan.exe" had some error and gives you a long number reference thing - i can't remember what it was, but it looks like this(or might even be this):

what kind of error checking? like when the user tries to put a king on a 7? you can use a method to check that and if the user is being a moron, then you can display a joptionpane or you can throw ...
