Something like this: fifth_letter = the fifth letter in MONTY , which is "Y". below is how to do it in code

fifth_letter = MONTH[4] use fifth_letter = "MONTY"[4] // i am sorry for the mistake! 

// 4 is the index of the letter "Y" , which is the fifth letter in "MONTY"

Hello Miss,

You have to remember that a String is an array of characters. What it is trying to demonstrate is how an array of any type works so let me demonstrate.

In any array, the first position of that array is always 0. So let's say for instance we have a String literal (which is just a String) that is "Hello". We already know that String is an array of characters, so the character in the first position (or position 0, is H), position 1 is e, position 2 is l, position 3 is l again, and then position 4 is o.

Please keep in mind that each String is comprised of an array of characters or char.

Just noticed someone else responded to you, please do check his edit as the proper answer would be: fifth_letter = "MONTY"[4]

Please try and see if that works.

Hello guys, is this thread turning into a snake thread python from java? i am ophidiophobic, just the mention of snake or anything that has to do with it can make me vacate this thread speedily (@mach 5) .

LOL no, the Goddess earlier asked some questions about it and being the foot slave/boy the gentleman that I try to be towards beautiful women, I tried to be courteous and answer the question(s).

With that said, I'm just waiting on the others to formulate correct solutions to the problems given, I see there has been an update to one of the answers, I will check it out soon, but right now reading books on machine learning and stuff. So I'll be back later. The next lesson will be about Arrays. So be ready.

AI stuffs i guess. i like AI books but they are so confusing to me. as 4 arrays, i am everly ready .

AI stuff is all about understanding how different algorithms work. Did you study Comp sci in Uni? or if you are in Uni, I recommend Comp sci or Comp Engineering. AI is purely mathematical and algorithmic in my opinion.

I wasn't opportuned to further my studies, and i don't think i ever will (i leave that for 'su kaabe').

i am currently studing(@leisure time) design patterns with java after which i will dive into bot programming with java. i am just so addicted to reading codes and anything that has to with computers during my leisure hours.
thanks for this lovely thread.

thanks for this lovely thread.

I urge you and encourage you to go back to school if you ever find the time and money to do so. I know everyone has their reasons and I know you are quite an intelligent individual, so please never give up. It's never too late. I don't know how old you are personally and I know that it is none of my business. But there are reports of men in their 70s getting their degrees and I assume that you are much younger than that.

OMG 70'S.

Well, i am: ((X<<1)+(105 mod 100))
where x = 100/10.
and i am already feeling so old.

I am sorry @crotonite, for I am the one holding us back. I finished the corrections based on the advice of oga Fulaman198, since yesterday. I will hasten to post them one after the other, in a separate post, so we could move ahead.
Oga, Fulaman198, here is assignment 1 Day 5:


import java.util.Scanner;

public class Convert{

public static void main(String[]args){
int count=0;
int selectedConversionUnit = 0 ;
double centimeter;
double celsius;
double naira;
double meter;
Scanner stdio = new Scanner(System.in);
while(selectedConversionUnit>=0) {


System.out.println("Please enter a digit here:";
selectedConversionUnit = stdio.nextInt();
count++;
switch(selectedConversionUnit){



case 1: System.out.println("Please enter a value in centimeter here:";
centimeter = stdio.nextDouble();
System.out.println(centimeter + " " + "Equivalent in inches is:" + " " + centimeter/2.54 + "inches";
break;

case 2: System.out.println("Please enter a value in meter here:";
meter = stdio.nextDouble();
System.out.println(meter + " " + "Equivalent in feets is:" + " " + meter/3.28 + "feets";
break;

case 3: System.out.println("Please enter a value in Celsius here:";
celsius = stdio.nextDouble();
System.out.println(celsius + "C" + " " + "Equivalent in fahreinheits is:" + " " + 32+(9/5)*celsius + "fahreinheits";
break;

case 4: System.out.println("Please enter a value in Naira here:";
naira = stdio.nextDouble();
System.out.println( naira + "Naira" + " " + "Equivalent in Euros is:" + " " + naira/227.96 + "euros";
break;

case 5: System.exit(0);
break;

default:

}

}
}
}

Alternatively, using if-else-if-else flow control statement, assignment 1 Day 5 will look like this:


import java.util.Scanner;

public class HelloWorld{



public static void main(String[]args){
int selectedConversionUnit = 0;
int tries = 0;
double centemeter;
double cmresult;
double metres;
double ftresult;
double celsius;
double clresult;
double naira;
double nrresult;
Scanner stdio = new Scanner(System.in);

while(selectedConversionUnit>=0){
System.out.println("please enter a value here:";
selectedConversionUnit = stdio.nextInt();
tries++;

if(selectedConversionUnit==1){
System.out.println("Enter your value in centemeter here:";
centemeter = stdio.nextDouble();
cmresult = centemeter/2.54;
System.out.println(centemeter+ " " + " equivalent in inch is " + " " + cmresult + "inches ";
}
else if(selectedConversionUnit==2){
System.out.println("Enter your value in metres here:";
metres = stdio.nextDouble();
ftresult =metres/3.28;
System.out.println( metres + "equivalent in feet is: " + " " + ftresult + "feets" );
}
else if(selectedConversionUnit==3){
System.out.println("Enter your value in Celsius here:";
celsius = stdio.nextDouble();
clresult = 32+(9/5)*celsius;
System.out.println(celsius + " " + " equivalent in fahreinheits is " + " " + clresult +" " + "fahreinheits.";
}
else if(selectedConversionUnit==4){
System.out.println("Enter your value in Naira:";
naira = stdio.nextDouble();
nrresult = naira/227.96;
System.out.println(naira + " " + "equivalent in euro is " + " " + nrresult + " " + "euros";
}else if(selectedConversionUnit==5){
System.exit(0);
}
}





}













}


Sorry o! I don develop some kind of bias towards if-else-if-else control statement, so, include am

And the assignment 2 Day 5, I hope I dey right:


import java.util.Scanner;
import java.lang.Math;

public class Guess{

public static void main(String[]args){

int count = 0;
int numberGuessed = 0;

int randomNumber = (int)((Math.random() * 100) + 1);
Scanner stdio = new Scanner(System.in);

while(numberGuessed!=randomNumber){
System.out.println("Please guess a number between 1 and 100";
numberGuessed = stdio.nextInt();
count++;
}

System.out.println("You win! After" + " " + count++ + " " + "times" );








}


}

Which maths topics does one need to do programming? Cause I read somewhere programming requires math skills

This is what I came up with guys.

//i couldnt use the math.random thing so i used
//what i know how to

import java.util.*;
import java.security.SecureRandom;

public class Guess
{
private static int guess,count,comGuess;

public static void main(String[] args){

SecureRandom rand = new SecureRandom();

Scanner input = new Scanner(System.in);
count = 0;
int x = 0;

while(x != -1){
System.out.println("Enter a guess between 1 and 100";
guess = input.nextInt();
comGuess = rand.nextInt(100)+1;

if(guess == comGuess){

System.out.println("You win!!!\n";
System.out.printf(" computer guessed %d%n%n",comGuess);
count++;

System.out.printf("It took you %d guess(es) to win.",count);

x = -1;

}else if(guess > comGuess){

System.out.println("Too high, try again!";
System.out.printf(" computer guessed %d%n%n",comGuess);

count++;

}else if(guess < comGuess){

System.out.println("Too low, try again!!!";
System.out.printf(" computer guessed %d%n%n",comGuess);
count++;

}

}

}
}

I thought you said you were learning html and css?
If you're done with those, can you show me some of the websites you've created with those two?.

If you don't have any projects created, then I urge you to create some to know how much you know(or how much you don't know) of those two then decide if you want to learn another language.

Logic, Flowchart and sliderule.

But ur logical sense of solving problem will help u.

Algebra And Calculus would be an added advantage.

I will jus learn ruby python is too confusing for now

It is not about changing from Python to Ruby.
All of them are thesame[C-based languages].
Since u wanna go into Web Development, I'll advice u go with HTML/CSS.

If u are done!
Go and practice.
When praticing, and u are getting better, u should start learning Javascript - Which is a Programming Language.

d fun part of learning Javascript at thesame time practicing HTML is dat Javascript code are implemented in HTML - <script></script> tag - which help u getting familiar with Html mre and mre.

If u are good with d three languages [HTML/CSS/JAVASCRIPT].
U can learn a scripting languages like python, Ruby, php, asp.Net e.t.c.

What will make ur learning of any scripting language fun is the knowledge of Javascript u earlier had.
So what u will nid to strt creating Web Apps with the scripting languages is their framework like Django(python), Ruby on Rails(Ruby) e.t.c

Wit knowledge of a SQL u re good 2 go!!

Good morning everybody Oya make una wake up, I see teacher dey come class. Shebi na 2day in dey teach us arrange....sorry...erm...wetin be the name self....hit head and stamp feet on the ground...Ok now I don get am. Array.

So dis guy too don tey for the game. Thumb up bro. Come o! This one wey our teacher never show face so, hope say that fine lady never carry her feet match our teacher face o Bia, Sugarhugs, come explain yasef before we pronounce you guilty.
You know say, the instruction was to put feet on his face, no go match our oga face o

This not to derail the thread,but it is rather good to share knowledge,
there was a time i was hell-bent on solving simultaneous equations(2 sets and 3 sets) with Java,
all the code i saw online were to cumbersome,
so what i did was that, i took my mathematics textbook,i did some derivations and i programmed the steps,elimination method to be precise,used in the textbook;
i added few exceptions just in case u get a value like (2/0 or y/0 or x/0); i include that also in the program .
Lemme share the code with you guys,it is my own personal code.

i will share 3 equations later.

this is for 2 equations

package beginner;
import java.util.Scanner;

public static void main(String args[]){

Which maths topics does one need to do programming? Cause I read somewhere programming requires math skills

Hello dear, some aspects of programming does, especially gaming programming and understanding recursion. This is simply more advanced programming. For instance, if I wanted to write a while loop which would take 15 lines of code, I can probably do it in 5 lines of code with Recursion.

Some aspects of programming (especially if you ever take a data structures and algorithms class) requires understanding of Discrete Structures and Linear Algebra. If you ever get involved in advanced 3D games programming, you would want a good understanding of physics and calculus.

BTW, here is another link for Python, I hope that you have better luck with this: https://www.coursera.org/learn/python/home/welcome

@Antonineutron and @the comedian satmaniac lol I will grade your assignments hopefully before tomorrow, I'm caught up in a storm of stuff right now. Please bare with me, I will hopefully have them graded no later than Wednesday.
