ok! i made it String??

Check Out The New Code

Your solution is correct. I think I should create a server where you guys can submit your work therefore people can't get answers from others.

Fulaman198 I have a question I sent to you in PM as I don't want to derail the thread. Thanks

Ok let me know when you send it. Thanks!

I've sent it

Yes you can absolutely, learning programming by yourself is very possible, but learning the science behind it requires extra research. It's all about understanding how to form algorithms.

In regards to your earlier query of why I can't teach this in Hausa for Hausa speaking people and Fulfulde for Fulani speaking people, it would be nice, however the people I'm addressing here are all Nigerians and other Africans. I'm not here to be an ethnic lion for the Fulani people. I'm here to try and help others from the great continent learn about an important programming language. I hope that you understand.

i know , i wouldn't understand myself ...

fulaman198 can i use notepad++ for the coding?

Yep you can I'll update the thread again later today

Wait ooo... For how long are you gonna keep changing the name of the thread? Day 1,2,4... Till day wetin? I'm suggesting you just give the thread a constant name so you don't have to change the name everyday.

Fulaman198:

oh good. and how do i compile it in cmd.. i copied and pasted what you wrote in my cmd but it gave me error...

juma'at kareem

Nice and understandable tut. Following.

No p.


I hope u can continue this tut to where we can create simple Apps; servers e.t.c.

How did you make this so simple? God thank you for showing me this thread. Thank you fulaman!

MuhdG:

juma'at kareem

that's strange how did you attempt to compile it in cmd can you post screenshots of your code and also your command prompt? Thanks! I actually recommend that you install Netbeans IDE to make things easier. But if you want, you can use a combination of your preferred text application and command prompt. Please post your screenshots.

ANTONINEUTRON:

No p.

I will continue it, I'm sorry I have been so busy today, I'll update it with more content tomorrow.

This won't compile because you don't have a primitive identifier you only did private static num1 and private static num2. Check your declarations again.

Thanks for the suggestion, I'll keep that in mind.

My assignment tisha come mark am now.

It's correct although you used different values than what was assigned. Good job though regardless.

Ladies and gentlemen, I will update the thread later this evening I hope. I'm so sorry that there have been no updates for the last few days.

Hello Dear,i need your help in this thread desperately.

debugged back-2-back. tnx

Following.

private static num1 needs to become private static int num1 same goes for num2. Your declarations didn't have identifiers

I was just excited at the way you are literally putting java concept into our skulls that I couldn't see the variable values given by you. Anyway, It's been taken care of.

Sugarhugs:


Sure! I can purchase enough data and also will follow up on this very soon, because I'm so busy so I just hope this will be up for a while till I can settle down to learn it

Hey, if you're interested in programming, you can check out onyenkuzi.com.

Ayyo, it's not a big deal ROFLLL. Don't worry about it. I'm actually a bit glad that you changed the literal values. Good job

Day 3:

First and foremost, I would like to apologise for not updating this thread for days. I have been quite busy with so many things in my personal life but i have not forgotten about you fellow Nigerians and other Africans. With day 3, I wanted to discuss the JVM (as you recall it stands for Java Virtual Machine) and classes more.

When you compile a Java file (of .java file extension), the resulting file becomes a .class file which is not human-readable. This same .class file is however what is read by the JVM. The class file contains what is known as bytecode. See examples below:

screenshot 1 is of a .java file which is what we as coders write. Screenshot 2 is of the .class file which is the resulting file that the compiler creates for the JVM.

We have briefly discussed one way out outputting text to the console via the System class (System.out.println). Today, we will discuss how to input data via the Scanner object. The Scanner object is one the class files (object files) that allows one to get scan for input. To use the Scanner class, we have to import it. It is one of the several APIs(Application Programme Interface) built-into the JDK (Java Development Kit). The API is a library of classes found in Java. When you become more sophisticated Java programmers, you will be able to develop and build your own APIs for other programmers to use. Let us get back to the Scanner class.

One of the various jobs of the Scanner class is to allow the programme to capture input from the user at the console. I have gone ahead and made a simple programme demonstrating the user of the Scanner object in the Screenshot below. Please view the comments to see what the programme does.

As you can see from the screenshot when the programme is run, you get a screen prompt and a series of questions.

I wanted to also mention something that I had not mentioned earlier in regards to the manipulation of strings. I have been so caught up with so many things. In computing science, manipulation of Strings can be quite important. However, often our work calls for the joining of strings. We call this joining of Strings "String concatenation." Here's an example from the programme that was written:

System.out.println("Your name is " + userName + " and you are " + userAge + " years old." );

In Java, one way of concatenating Strings is to the use the '+' symbol in order to join text and values together.

Today was a rather short lesson on input and output and further information on the JVM. In the next tutorial, We are going to be learning about Conditional Statements (if - else if - else) and switch and we will be writing a programme that involves the utilisation of conditional statements.

As for your assignment, I would like for you to write a programme that prompts a student user for their name, and 4 test scores. With the information gained from the 4 test scores, I would like for you to calculate the median (average) of the 4 test scores and output it back to the user alongside their name.

Example: "Onyewu, your average test score is 84.8" for the output. Please use type double for the test scores and not int. Thank you!
