At long last. . . . . .you forgot to add that he is a better programmer than dhtml18!

Well most of his work is original stuff, so you can be the judge of that. Its the thinking behind is solutions that makes him a good programmer. Programming is more about you go about trying to solve the problem.

Chaiiii.
Even as much as I know that I'll surely get to this advanced stage you guys are talking about, I'm already feeling the heat while still in the curve. Doing this learning alone can be daunting and depressing.

Yah, and dhtml18's work are pirated stuff, and poor thinking behind his solutions. . . .you forgot to mention that too (you are really improving your analytic skills small small)

Well, professor seunthomas can teach you - he actually has a phd in programming (or so i have been told).

That'd be great o.
What about you nah? Its not by phd o.

I will really appreciate the input of senior developers on this forumn on their hiring experiences in Nigeria, as well as steps in this article they do not agree with.

Hello larisoft, your post is one of the few posts I enjoy reading on Nairaland, especially, here in the programming section. Although, this piece may not be of use to me, as I am just starting out as a beginner in programming, That will not deny me the privilege of accessing your assistance and that of other programming gurus here. In my quest to learn programming, I picked Java and I have been quietly studying some books as well as watching some videos I got from the internet and off course, I put what I learnt into practice. As you know, a beginner like me will encounter some hitches or challenges in the form of errors in my written codes, I am currently having issues with my java class methods.

The problem is that I have been trying to no avail, to make my java class method work. For example, the math class like Math.random(); or Math,sqrt(); refuses to work and have been displaying this error: "Can not find symbol System,out.println(Math.random(number)); Symbol: random(int) Location: class Math " I really need to know why it is displaying this error. Below is the entire code:


public class Math
{
public static void main(String[]args)
{
int x = 100;

System.out.println(Math.random(x));

//System.out.println(Math.sqrt(x));
}
}

This error is driving me nuts, save my sanity........

Ccc larisoft, dhtml18, seunthomas, Danielthegeek, asalimpo and others.

Ideally, you ought to create a separate thread for this: but this should work:

import java.util.*;
import java.lang.*;
import java.io.*;

class MathDemo
{
public static void main (String[] args) throws java.lang.Exception
{
int x = 100;

System.out.println(Math.random()*x);

System.out.println(Math.sqrt(x));
}
}

However, the phD professor might have other views.

Dhtml18 already answered the question partially. but you may still benefit from me explaining why the code doesn't run.

1. the name of your class "Math" conflicts with the system static class "Math". You should rename it to "MathDemo", or "MyMath".
2. You have not imported the java.lang. library which houses the Math class.
3. MOST IMPORTANTLY: your use of Math.random is wrong here. the Math.random function does not accept parameters. It simply returns a random double value between 0.0 and 1.0.

Thus: this will work (using your code)

//import the Math library .

import java.lang.Math;

//Math changed to MyMath

public class MyMath
{
public static void main(String[]args)
{
int x = 100;

//changed this (formerly System.out.println(Math.random(x)))
System.out.println(Math.random());

//this will work fine now
System.out.println(Math.sqrt(x));
}
}


Good luck, bro. You wont regret learning Java. You can be sure of that.

^^^thank you jare, I knew there were professors (real ones at that) that will do a better explanation than my trolling self. . .

Thanks, bro.

@satmaniac
in addition, you should download the java api documentation that corresponds to your jdk version from sun Oracle's site, unzip it and keep it handy for api reference lookups. It will save you tonnes of headache in the future.

and also save him from committing suicide. . .

@asalimpo, dhtml18, and larisoft, I am very grateful of your kindness and generosity and I am also sorry for posting it here instead of creating a thread. Make una no vex, una know say for programming una be elders and me be una last born. Una kukuma know say last born tend to misbehave sometime, so, make una no binu oh.

Judging by your responses, I have no single doubt that I am in good and capable hands. Thanks, once again, elder broses.

Now, let me go try it out, I will report what transpire ASAP.

dhtml18:

Hehehehe.......Suicide indeed. The thing frustrate sotay I come dey reason am say na one old witch dey responsible oh. This my African mindset sef.

I know of many people that started out well in programming but quit later as a result of frustration.

Grateful for your contributions, it worked after implementing what you recommended. However, I will want to know why it didn't work even after using "import java.util.math". I mean why would "import java.lang.math" work and "java util.math" refused to work?
@asalimpo I will make sure I do that as it will save me needless headache.

because there is no package "java.util.math"

there is also no package named "java.lang.math"
what you have is a class "Math" in package "java.lang" . its full canonical name is "java.lang.Math"

Oh... got it man. Thanks!

asalimpo:
I share your sentiments.
But i think a programmer should know some computer science, at least data structures and their runtime performance. Knowing how to create some custom data structures : linked list, trees, maybe graphs-
is a big plus , because all programming problems are simply algorithms manipulating data structures.
The rest are just icings.

Hi Bro,

There's actually a difference between Computer Science (which of course demands algos and data structures) and Software Engineering (which is what we think of as programming). The fact is that software engineers or developers or programmers (if you prefer) really do not need to know algos/data structs, what they need to know is how to apply the principles of software engineering throught he channel of their tech stack to solve a given problem.

For instance, every major programming language has built in data structures and algos implemented which may be quite different from what is recommended in comp sci. e.g. the sorting algo which google chrome implements for javascript is quicksort, but mozilla implements mergesort!

What should a developer do? Simply call 'sort' and allow the run time to determine how best to handle this.

Yeah, there's a difference but knowing only how to use pre built products - framework/libraries - doesnt
qualify you to bear the title "software engineer" . People who can only cobble together libraries are called
code monkeys/"programmers" in a derogatory sense.
Software engineers, are very sound mathematically, and very hands on. Can architect large applications and know enough science to judge efficiency of algorithms they use.
I know the term has been bastardized by every tom dick and harry coder but your example falls way too short.
Anyway, the more math you know, the more fundamentals you grok, the deeper your insight and the more original your products can be. any aspiring coder should aim to go higher.

Bro? Why you always sounding so upright and stiff?? Even Dennis Ritchie is not as rigid as you are and would condone these fellows you keep speaking ill of. No beef though but you should have left nairaland with the participants of this thread since obviously, those are your mates. Instead you're here forming oversabi old cargo. awon papa ndi one. Matchew!

if i'm opinionated it may be a good sign. Have you worked with linus torvalds and richard stallman?
In 2013, you didnt have a computer to compile code on! and was looking to get into programming.
In 2016, you are here running you mouth. What dyu know?
come back in 10 years time and maybe your opinion may be different. As for now, you are simply ranting ...

This is you:

Muchecheche. ... is that your strongest punch?? hmmmm
Anyways make I give you small OT.....it's not when I wake up that matters but what I do when I finally wake
Like I said, I'm not beefing you, I always feel terrible seeing adults lacking common sense roaming about without control, looking for younger people to devour/manipulate So I tried giving you, a TIP If I beef you, you go see as body go do you.

There's actually some dude with a monicker starting with "d"(a real dick, that one) I was waiting to mention me on this thread. I had prepahd to tear him to shreds

mumu like you.
When you posted your first unfounded blab, i looked at your topics to see which ones were programming related-just to gauge you. And found none except the one i posted.
Your types are never above these level- stupid,clueless and with no ability to reason logically or say anything meaningful - so all you can spew and settle for is this: meaningless insults.

you can buzz off if you want.

We are in the programming section, if you are a younger person, or your age is an issue to you, feel free to state it in your comment - but more intelligent people wont see how that affects the validity of your arguments?
If you feel you are too old - then maybe the compiler may not compile your code - whichever way, it goes
, you are simply exposing your hollowness.

Go back to the initial post and state your points logically, then maybe it maybe it be more worth considering. For now it's trash.

Abeg! Instead of begging me to help you grope out of your douchebaggry, you're here beating your chest like the wild gorilla I thought you weren't. What is the relevance of my thread count in the current convo?? And who said I'm a programmer in the ist place I've been here for sometime and I noticed you speak very bad about upcoming and aspiring tech guys. Let me tell you; if you're a kind of person that derives joy from making people feel miserable and upset about themselves just because you probably started off earlier than they did and think you know better than they do, you're worse than the principalities and powers that suck blood at night.

I'm not saying you're a principality and power though but judge yourself. And please, bye! I've gotten it off my chest so you can continue wallowing in your misanthropic retch-inducing attitude with an rancour to the high heavens. *heaves

Uhm uhm

hmm... i see - you are the kind of person that crumbles under cold truth.. (aka criticism).

you want a compiler that wont spit out error messages!! Or a tisha without a cane.
3 years into programming and this is all you've contributed to nairaland!! olodo.

You can grow a thick skin or b*tch about it like you're doing here.
Check out the military - those guys go thru hell from their superiors and come out tough - that's y they can protect you.
You want sombory who'll do the assignment of every lazy punk who has a programming assignment at school?
If you dont like how i talk - buzz off. I'm not gonna change - for you.

Tozo! see your snout
nye nye nye nye nye nye...
Matchew!! self ordained nairaland programming section teacher. Shay na you put yourself on salary? jobless oloshi! no go fine better work. na your type as lecturer dey encourage mass failure for their department with this so-called "military mindset". Who's fighting you Only you teacher, only you prinspa, only you defender/attacker of the galaxy. Nkapi

And BTW I no be programmer o! I dey sell undies and condoms for Onitsha main market Abi does frequenting here automatically make me one?

I wish you guys wish turn some of these your arguments into useful codes for me.

Agbero , see as smileys full em comment .You've really seen something you really like doing ...
insulting/fighting.
B4 now, you were a nonentity here.

#Lets play i've got all day...

OMG!!! I missed this beef.

#Lets play i've got all day...

Why not go to the daycare or crèche so you can play to your heart's content? mmmm? You no dh even shame to announce say you get time "all day". But hey! What did I expect from a jobless barrack hoodlum

If you dont like how i talk - buzz off. I'm not gonna change - for you.

You've actually acquiesced to the fact that your attitude is rotten and smelling all over this section but instead of simply asking for help (which mustn't even come from me), you're busy foaming in the mouth. Do you think you're doing me I'm trying to train you in a proper manner since it's obvious your parents failed miserably in your upbringing. Teach you one or two societal etiquettes and a little decorum since your condition is now our collective responsibility. You're being obstinate and unnecessarily petty all over the place.
