I think that egoless programming is probably an oxymoron: the only programmers that can and do laugh at their awful code know that their code is actually head and shoulders above anyone else's.

Why is my text all red up there, that's happened before?!?
I am still beating the beast even after reading the information, and I surely appreciate it. I learn by accepting critics, I get it from the professors, I see you guys as professors within your own means, gt it here as well
Truth is I am still going to ask questions, rest assured I am not calling myself Java programmer until I can actually write this stuff, for now, I am modifying the works of our great professor, making up a desgn that best attack the lab she has set forth. I try to find bits and pieces of code from past and even future labs to give her what she needs, then I come here and talk about it.
My friends, I still cannot shake it...
I will attempt to load a zip containing only the design, the original code called for fixed array:
[CODE=JAVA]
Person[] person; //declare the person array
person = new Person[5]; //and then create it
[/CODE]
As shown, the code beyond this one was with the help of the professor and you, but it got interesting when I had to make it work when I went to work on the ideas I got.
Will post later, being pulled away here;-)
Thanks!

That's because you have included code which had unbalanced quotes in it.Originally posted by Dököll
The code-specific tags are not 100% so when your code stopped in the middle of a string, they didn't handle returning from string mode when the tags were closed.
Fixed now - but you may want to look at what you're posting for clues like that. It may also help you to fix some code possibly. I'm no Java expert so I can't be sure on that one ;)Comment

What do you know, pretty simple, thanks on that... I'll fetch my other one and attempt to fix it. Yes will let you know if I cannot fix...
Thanks again NeoPa!

It was my last day today at work, pretty somber leave but my colleagues were so nice, I could not begin to tell you... thing is they understand my having to go, it's actually for a Java position, I am being paired up with folks who know and will be sent to training, pretty interesting quite honestly, seems like it's all falling into place. I am babbling but I am happy that the group I left is even now stronger, moved up to a bigger IT division, which we had to contact now and then for the more specific IT stuff, we're/my colleagues are now right there. I don't feel so bad anymore, send my boss the code library to the database built for the clan. Hopefully I did not leave any work behind, tried not to, 'til the last hour, should be okay, I think:-)
On a different note, here is what I could salvage out of my design, could not do the zip, silly me:-)
I have a long way to go, I got some leads on getting the program to loop for more entries. I am attempting usng String [] out of my:Code:Köll S. Cherizard Lab 7 Version 200800000408 Automobiles need to be entered via pop up menus or else. Entries at this point should dictate size of array/InputDialog pop up in the program; if user enters 1, only 1 automobile should carry ratings of three types, ID and name should also be vital. Each automobile’s own ID, Rating ranging from Endurance, Dependability and handling, and name of each automobile must be stored according to number of instances added to array or InputDialog. Must enter speed of each vehicle, names and so on ought to further differentiate from Semi-Sporty autos to the Sportiest of them all. [B]IMPORTANT:[/B] Make available number format exception to fend off bogus data such as vowels, characters as a dash, period and more, in pop up menus. Sort data result or view using bubble sort method; add a search method, sort by user ID and search by auto name. Distinguish ratings to make available Semi-Sporty and Sportiest automobile average rating levels, display rating levels of either with Ids sorted. [B]Declare variables:[/B] NumberOfAutomobiles, AutoName, ID, Speed, Rating1, Rating2, Rating3 NumberOfAutomobiles as integer AutoName as string ID as integer Speed as char Rating1 as int or double Rating2 as int or double Rating3 as int or double Add Loop to make available for Rating Scale 1, 2, and 3 Use for loop to add Ratings one by one then find length of search, any type of user input, necessary to restrict user entries at this point. if automobile Rating1 less than average and is specific to the name of auto for Rating1 and data valid, user has found a Semi-Sporty Auto Automobile if automobile Rating1 higher than average and is specific to the name of auto for Rating1 and data valid, user has found a Sportiest Auto Automobile [B]WARNING: [/B] The ratings will need match ID numbers of each auto Add a bubble to sort by ID and bring in a linear search option, it's a must Add Loop to fetch all automobile added into the program Use for loop to search and find length of text user need searching, compare against already added data to InputDialog. [B]IMPORTANT: [/B] The ratings will need match ID numbers of each auto Add a bubble to sort by ID, and bring in a linear search option [B]TO DO: [/B] Add/distinguish Rating 1 from Rating 2, and so on, and output ALL separately for all to see… Make program scalable in case you need to add stuff; build templates if needed… [B]RESEARCH:[/B] · Use LAB6 for fixed-array code – in class lab · Use Book for undefined array examples – homework # 5 example · Use LAB 5 for Number Format exception – in class lab · Use entry instances to determine array size – user InputDialog · Use bubble sort method near the end – Discussion, Web site search · Use Linear search method code example – discussion, Web site search · [B]MISC: [/B] Print to system of MessageDialog
[CODE=JAVA]
public static void main(String[] args) {
...
...
then adding an istance where it should fetch/equal entries made
String[] drivers = new String[numTypeAuto];
Something like that...
[/CODE]
Still researching, but please jump in, I could be doing this in a simpler way.
In a bit, and thanks for everything. Wish me luck on 2morrow;-)

Good heavens I did it again, UNbelievable:-)
Alright, let me figure this out...Comment

Now that it's fixed, above does not make sense... My text was red again, so I removed the JAVA, not sure why I had to do that there. Anyway, thanks NeoPa, I re-read your post and I nailed it, it seems:-)Originally posted by Dököll

No worries Köll.
I'd suggest checking the code you post first though. It's possible to get around the problem using simple [ CODE ] tags (text) rather than the Java ones, but as we all (developers) know very well, understanding and fixing the root cause of a problem (the code posted) is far more reliable than always skipping around the problems caused.
Think of it as more of an opportunity to find bugs than as a problem posting.Comment

Below was in the wrong portion of the code, I asked for the integer to grab instances which would help determine size of array then I grabbed everything before looping through, thus
[CODE=JAVA]
Automobile[] automobile; //declare the Automobile array
automobile = new Automobile[numTypeAuto]; //and then create it
for (int i = 0; i < automobile.leng th; i++) { //create a new Automobile and assign values
[/CODE]
Should be right after user has entered number of automobiles to work with:
[CODE=JAVA]
//read in data values
numTypeAuto = Integer.parseIn t(JOptionPane.s howInputDialog( null,"Enter Number of Automobiles:")) ;
Automobile[] automobile; //declare the Automobile array
automobile = new Automobile[numTypeAuto]; //and then create it
for (int i = 0; i < automobile.leng th; i++) { //create a new Automobile and assign values
autoName = JOptionPane.sho wInputDialog(nu ll,"Enter Favourite Automobile name:");
autoIDNumber = Integer.parseIn t(JOptionPane.s howInputDialog
(null,"Enter Automobile ID Number:"));
[/CODE]
It should not be added as this...
[CODE=JAVA]
Automobile[] automobile; //declare the Automobile array
automobile = new Automobile[numTypeAuto]; //and then create it
for (int i = 0; i < automobile.leng th; i++) { //create a new Automobile and assign values
//automobile[i] = new Automobile( ); // don't need this here
automobile[i].setSizeOfArray ( numTypeAuto ); //create user-defined number of Automobiles to be entered
automobile[i].setAutoName ( autoName ); //create instances of each favourite new Automobile
automobile[i].setAutoID ( autoIDNumber ); //create instances of each favourite new Automobile ID number
automobile[i].setRating1 ( rating1 ); //create instances of each favourite new Automobile rating scale 1
automobile[i].setRating2 ( rating2 ); //create instances of each favourite new Automobile rating scale 2
automobile[i].setRating3 ( rating3 ); //create instances of each favourite new Automobile rating scale 3
automobile[i].setAutoSpeed ( autoSpeed ); //create speed level of each favourite new Automobile speed
[/CODE]
I was getting one instance of an auto because my code never looped through anything. I'd already gotten what needed from each InputBox, so the code stopped after enterring 1 auto.
Now I need to use bubble sort example to see how to fit it in, wish me luck there:-)Comment

Truth be told, I think I stunk pretty bad for the last exam; I actually thought I had one more month, was probably sleeping, a lot of sleepless nights. I think I did alright in the final exam, have yet to see the scores, gbut should surely pass. Above code was satisfactory as is, will see what score I get, part of the code was in fact a topic in the exam......I was getting one instance of an auto because my code never looped through anything. I'd already gotten what needed from each InputBox, so the code stopped after enterring 1 auto.

One should never stop programming, by the way, if that's your thing, school is out, well really 'til September but... I have what I think is a puzzle, not relating to school, I figured why not include in this blog... I muscled through this bit of code from my book at work, it works wonders, what a surprise;-) Tried it @ home just to get curious, lo and behold, it does not work; is this because my system is not part of a network?
What do you make of it?

There was no need to post your code because the exception indicates that the
JVM can't even find your class. It's a classpath problem; your .class file should
be stored somewhere in a path /foo/bar/dbMailMePackage/MailMeSolid.cla ss.
Then your classpath should contain the directory /foo/bar/

[QUOTE=JosAH]Very cool Jos, thanks for your input on this one!Originally posted by Dököll
I wanted to demonstrate that indeed a class does exist, I just could not figure out why it was saying it is not there. So .class is not where it should be eh!
Super, let's try that, thanks Jos...
