Fill an array with random numbers
arrays, java
Solution
You need to add logic to assign random values to double[] array using randomFill method.
Change
public static double[] list(){
anArray = new double[10];
return anArray;
}
To
public static double[] list() {
anArray = new double[10];
for(int i=0;i<anArray.length;i++)
{
anArray[i] = randomFill();
}
return anArray;
}
Then you can call methods, including list() and print() in main method to generate random double values and print the double[] array in console.
public static void main(String args[]) {
list();
print();
}
One result is as follows:
-2.89783865E8
1.605018025E9
-1.55668528E9
-1.589135498E9
-6.33159518E8
-1.038278095E9
-4.2632203E8
1.310182951E9
1.350639892E9
6.7543543E7
Problem
I need to create an array using a constructor, add a method to print the array as a sequence and a method to fill the array with random numbers of the type double. Here's what I've done so far: ``` import java.util.Random; public class NumberList { private static double[] anArray; public static double[] list() { return new double[10]; } public static void print(){ System.out.println(String.join(" ", anArray); } public static double randomFill() { return (new Random()).nextInt(); } public static void main(String args[]) { // TODO } } ``` I'm struggling to figure out how to fill the array with the random numbers I have generated in the randomFill method. Thanks!
