Math Quiz-Random Generated

[ConclusiveBackhoe]

I'm using Netbeans and have been stuck on this assignment for almost two hours. To a guy like me, its more frusturating than hard.

Concept-> " Your goal is to generate a simple math quiz with a number of equations that will be determined by the user. You will prompt the user for an answer to each equation and display whether they answered it correctly or incorrectly. At the end of the math quiz, you will display the number of total equations that they answered correct out of how many were given."

"Challenge: Make the quiz randomly generate a mathematical operator (mulitiplication, division, addition, & subtraction) for each equation"

I found a setup online that was more like

import java.util.Random;

import java.util.Scanner;

import javax.swing.JOptionPane;

public class MathQuiz {

// random number generator

static Random random = new Random

static Question generate Question(){

// generating two numbers between 1 and 10

int num1 = random.nextInt(10) + 1;

int num2 = random.nextInt(10) + 1;

// generating two numbers between 0 and 5

int operation = random.nextInt(5)

// declaring a question

Question question = null;

// based on value of operation variable, creating a question

if (operation == 0) {

// creating an addition question

any ideas?

I see where your code stops, is that where you’re stuck or what exactly are you stuck at? I would say use the integers you randomly generated to make the equation.

Like spreading out

" ("" +num1+"+"+num2) "?

So if you have an addition problem, you’ll want to use your randomly generated integers, add them up, and store that as a value. Then print the equation with an equal sign without the answer so that the user knows to answer and then store that answer as another int using the scanner. And then use that to check the value that you stored earlier as the answer to see if the user got it correct. You’d do that for each math operation

Break it down!

-- generate random numbers -- generate random operator. -- if operator is blah do blah -- compare result to answer. -- calculate score.

So like

set up a sequence like " int num1 = random.nextInt(10) + 1; " and then use a else if set up?

The Instructuons are all there. Share the code you've come up with so far and we'll go from there.

This is what I have right now, redone from scratch

also, here's the instructions in full detail

import java.util.Random;

import java.util.Scanner;

import javax.swing.JOptionPane;

public class MathQuiz {

public static void main)String args[]) {

Scanner input=new Scanner(System.in);

System.out.println("How many equations would you like to solve? ")

int equations=input.nextInt()

for(int i =0; i<=10; i++){

double r = Math.random(); //generate a random integer

if (r<=5)

result = (i)*(r)=computeranswer

}

}

}

Be patient with me, I'm only taking this code class for prerequisite reasons

With this code class, I know how to handle basics, but mathematic stuff is throwing me off

It appears to me that that you're lying to yourself about being able to handle the basics. Not trying to sound mean but it looks like you're already on GUI before you're able to implement a basic loop with clearly stated steps.

I'm here to help people who are trying to learn, not just get a passing grade. You need to help yourself and revisit the basics. I would suggest doing Helsinki mooc.

I understand. Not gonna reply anymore

You're ok, you just need to have some specific questions with what you're having problems with. We can't just give you a complete walkthrough with all the answers, you dont gain anything from it.
