Don't come here and use your medicority to dent the image of erudite scholars. Professor Charles Soludo obtained his three
degrees and then professorship at the
University of Nigeria in Nsukka, Enugu State.
He graduated with a First Class Honors

degree in 1984, an M.Sc. Economics in 1987,
and a Ph.D. in 1989, winning prizes for the
best student at all three levels.

pweetyz: ..i actually thought as much..cos you perhaps type like one coupled with all your computer stuffs buh your email got me thinking..seriously??..JAVADIVA..are yoi a goddess

oh that!...Belonged to a friend, it was dormant so i used it to register on Nairaland rather than going through the stress of openining a new one. LMAO @ goddess

pweetyz: ..are you male or female..

Male

why do you ask?

pweetyz: i just told her and she said shez already done that..she was told that it can't be changed..i.e..jamb does not offer any changes..i guess we'd just opt for the age declaration ish

I thought as much, tell her to get the affidavit before clearance starts and she should try as much as possible to start her clearance on the first day of clearance. This correction is a tedious process, so the earlier she starts the better for her.

Tessy10: isn't it possible 4 one to use d L.G.A age declaration in place of d birth cert.?

No. It has to be from a law court.

pweetyz: ..I'm lost..i don't understand a thing not to talk of explaining it to her..okay lemme explain better..
her date of birth is the same on her waec and date of birth cert..but it differs in her jamb and putme since same data was used..so the question is..how can she correct her jamb's date of birth to make it correspond to the ones on their waec and birth cert..thanks

Well, one way to get it resolved is what someone has just said, go to JAMB and get it rectified but i don't know if that can be done or how it can be done. Now let me explain better, If the Date she used on her Jamb is not much different from the one on her Waec, she should go to a law court and swear an Affidavit of Age Declaration declaring that the date on her Waec is her correct date of birth. When clearance starts in school she would then be asked to fill a 'correction form'. Her date of birth would now be altered to reflect the one her Waec, like i said the process is quite tedious. Hope you are now clear?

pweetyz: Please you guys should help a pal out..
a friend of mine has a problem with her date of birth..the date of birth on her jamb does not tally with the one on her waec and other certificates
please is there any way she can correct this

It depends, what is the date of birth on her Waec and that on her Jamb? If the difference is not much she should go and swear an affidavit of age declaration bearing the date on her Waec. When clearance starts she would be asked to fill a correction form to reflect the date on her Waec. This process is quite tedious but would resolve it. If the difference is too much her admission might be revoked, lets hope it doesn't come to that.

pweetyz: ..I think i know vher..phones not so good though so my whatsapp nd facebook are sorta inaccessible..i stay at d/line though..plus i meant mr solomon earlier

Alright, i would send you a P.m. via Nairaland later on. Do have a nice time.

pweetyz: ..Charity house is another story now sef..8th position in thhe inter-house sports twice in a role..we're still the neatest though cos miss kalaya trained us well b4 we left..i doubt this set will continue vhat way though cos they didn't experience miss kalayaz touch..i'll miss that woman eh..sth terrible happened to her..she fell so ill after they re-shuffled the house mistresses..she had to stop school for a rili long time and i heard her tell iko that it was her mum who bathes..the once very agile miss kalaya is now like a broomstick..imagine an illness from my ss2 till i left nd shez still not owk.
the 2013 set spoilt the school completely..imagine ss3 students tuck in to dinning..we stopped that in our set sha..buh school was no longer sweet..i used to look up to owning school in ss1 cos of wah ah wz seein buh in ss2..it was just 4 d freedom..
well this present ma p is a money monger..the woman doubled our boarding fee..nd put so much load on the pta we started paying for meal subsidy..we also paid 1k for chickens on sunday..we eat hot meals now though cos they now use coolers not pots
mrs inoma is ever so cool and beautiful..although she neva taught me i still love her gentle nature..mr iko has been promoted nd transferred..heard hez going to be a vp in a school somewhere..mrs orumade was also transferred..miss solomon is the new snr boarding house master..luckily for this present set..ma p was promoted too..hope the new one won't be worse..
well fgc is less fun buh way more disciplined sha..it's all in the past though..now uniben all the way

Really sad hearing the Kalaya's story, heard she was sick but never knew it was this critical. She was a really nice person if you could look beyond her adamant nature. Lest i forget, i stay at Elelenwo in PH although i now spend the better part of my year in Benin. Can we hook up off Nairaland? Whatsapp? Facebook?

pweetyz: ..thanks dear..i'm certain ion know you though cos you must have left b4 i got admitted cos u guyz had your val in july nd the new students were admitted in september..might be a coincidence though..where in ph do you stay nd also what hostel in ekosodin cos i stayed at lively hostel during my pume
bdw..i was in charity house..do you know PERE??..your security prefect of your set..she was my school grandma..you guys enjoyed the school when it was fun nd wicked..while we just heard the gists..the rate at which teachers have excess rep these days eh..even corpers sef..FGC PH is truly a changed school..i think i'll forever miss it though..

loool. I was also in charity house and yes i know Pere. Yeah, we left before you guys came in. I also heard the school had changed a lot. Corpers?? Rep?? Looool. We were the last that really understood the tradition of that school. Perhaps you must have heard the school was once bad, it wasn't as bad as what you heard, it was worse! But change is inevitable and we saw it coming. We knew the school would eventually turn out like this. What about Ms Kalaya, Mr ikolodo, Mrs Inoma are they still there? Heard rumuors that Ikolodo was transfered.
Heard you guys even wore blazers and shoes to school and even your school fees were hiked. Damn!

I stay at Excel hostel at Ekosodin, very close to the back gate.

fingard02k: Thanks

The one i wrote didnt work. Syntax error was too much..just need some clue.
Its not an assignment or anything related to school buh something i wanna learn

Paste the code here.

pweetyz: .

I schooled at FGC PH, graduated 2011. School at Uniben, 200 level Computer Science. Grew up in Port Harcourt and stay at Ekosodin. I am not kidding. Congrats on your admission.

Could it be a coincidence? I doubt!

@MissMeiya can depression cause Anxiety Neurosis? If yes, how can it be cured or managed?

olukenzo: I am sure there is an explanation for the count++ at the end of your for loop. I didn't run your code, but I think its unnecessary. You'll have <10 iterations. Also, there is no need to calculate percentage in the iteration..

Did you read the o.p's post and code before making this comment?

OKAY, Let's start.

First of all, It is imperative for you to know that creating a connection each time a button is clicked is wrong in every way possible. You should put your connection statements in a method and place it in your constructor. So it establishes a connection as soon as the application starts.

So assuming the method is called InitDatbase()

Your code should be something like

void InitDatabase()
{

   try 
   {
        String host="jdbc:derby://localhost:1527/Employees";
        String uName="admin1";
        String uPass="admin";
        connection cont =DriverManager.getConnection(host,uName,uPass);
        Statement stmtt= cont.CreateStatement();
        String SQL="SELECT * FROM Workers";
        ResultSet rs3=stmtt.executeQuery(SQL);
    }
}

Then you call your InitDatabase() in your constructor like this

  public YourClassName
  {
        InitDatabase();
  }

Okay, i don't really know how you intend to make your app work. So i will touch a possible scenario i can think of. I am going to assume that as soon as the app loads it displays the first user in the database. To do this, you should create a method somewhere and probably call it firstUser();

In your first user method, do this.

void firstUser()
{

try
 {
       rs3.first();
       //get value
       string fname=rs3.getString(Fname);
       //set value
       txtFirstName.setText(fname);
 }

}
Now in your btnNextActionPerformed method, do something like this. This would work for the 'NextUserButton'

try
 {
       rs3.next();
       //get value
       string fname=rs3.getString(Fname);
       //set value
       txtFirstName.setText(fname);
 }

First of all, this is not a logical error, it is a run time error. You are most likely trying to utilize a variable you haven't initialized or a variable that points to null hence the 'NullPointerException'. I can't see the rest of your code but i suspect it is comming from the result set variable 'rs'. Check to see if it has been initialized and if it actually holds any value.

Compare and Contrast this code with yours. It should work now.

Take note of the changes i made including indentation. It is always cool to indent your code.

On a side not, There is no need to give your Package name and Class name the same name and also no need to write them in upper case letters.

Nice job by the way.

Kraze..

This song would have made me cry if Celine Dion sang it.

dmcdad: I'm glad that some peeps have started the season with losses. I thought they wanted to go for the sextuplets.

These kids of today think they can all do what Barca did. Smh

Sextuplets? They didn't even win la liga.

bykebyke: Nope..To destroy defences!!

As a replacement for who? Iniesta? Neymar? Suarez?

bykebyke: If only Real Madrid could sell Di Maria to us..

Damn

To come and grace our bench?

dmcdad: That guy is the worst defender around. Did you see how he was made to look like a player from Barca's Juvenile A? And yet some people would say he is more experienced than Bartra blah blah blah... Abeg where him wan put the experience again?

I am sure we would see more of Bartra than Pique this season, except he really steps up his game.

coded01: Ventiladores Cataluña!


What do you think about the line-ups above?


Which is your favorite?

Anyone without Pique is fine by me He was the only one that disappointed me last night

Antitrust, Hackers, Silicon Valley (The series)

elvis10ten: didn't see what you expected ?

Even worse, the number of ignorant people here is too damn high...

s.m.h

I create a hotspot with my phone and connect via wifi...

asalimpo: google will hav engineers researchg new products and concepts (software like bigTable, hadoop is math heavy. Oracle will employ devs to research new ideas. Samsung will hire devs to optimize its phone os.
Boeing will need engineers too.
They need higher math here.
They need math because the tasks demand it? If ur processing 1billion request per day/hr you need efficient algorithms to keep your server on.

Touché

Speaking of someone who accused me of quoting him out of context, you have just done your fair share of that. I never said you are an advocate of mediocrity and i never implied business softwares were average softwares. Sorry if i sounded condescending when trying to drive home my point, we are both scientist, we disagree to agree. I just disagreed where you said 80% of all the maths has already been implemented an most computer scientist would spend most of their career not applying the 'mathematical theories' they learnt in school hence i spoke of Network and Graph theory.
