I hope this helps . I need to generate a random number between 8 and 32. then multiply to the power of 2. then repeat it in a loop 10 times. I can't figure how to generate the number within a range this is what i have so far. , In plain english:
Math.random returns a number between 0 and 1.
code :
``````var random = Math.random();

var number1 = 5.0;
var number2 = 12;

var range = number2-number1;
var rangedRandom = range*random;

var rangedRandomPlusLeast = number1+rangedRandom;

var rangedRandomPlusLeastAsInteger = Math.round(rangedRandomPlusLeast);

will be helpful for those in need Ok, so the scenario is, I want to generate a list of 4 distinct random numbers which will represent 4 random choices for a quiz application. One of the 4 random choices will be the correct answer, so we will already know the index of the correct choice. This correct index or number must be included in the random number list. , For Java 6 and newer:
code :
``````final int maxNumber = 100;
final int numbersToGenerate = 4;

Random random = new Random();

// add as much random answers as needed, the usage of a set prevents duplicates
}

// convert set to list and shuffle it
``````
``````final int minNumber = 1;
final int maxNumber = 100;
final int numbersToGenerate = 3;

final int[] ints = new Random().ints(minNumber, maxNumber)
.distinct().limit(numbersToGenerate).toArray();

wish help you to fix your issue How do I generate a random number in Java, (using Eclipse) that is weighted towards certain numbers?
code :
``````public static void main(String[] args){
ArrayList<Integer> list = new ArrayList<Integer>();
int randomInt = list.get((int) (Math.random() * list.size()));
System.out.println(randomInt);
}

this will help Note that I have only tested the distribution of the random numbers using SecureRandom within Java SE. I'm reasonably sure that this code is correct though. The code uses the "simple reject" method defined by NIST.
So without further ado, the code.
