I have my following code working like this:
import java.util.Scanner;
import java.lang.Math;
public class Magiceightball {
private static void Number() {
int magic = (int) Math.ceil(Math.random() * 10);
String x;
switch (magic)
{
case 1: x = "Yes.";
break;
case 2: x = "No.";
break;
case 3: x = "The odds are in favor.";
break;
case 4: x = "The odds are against you.";
break;
case 5: x = "Never.";
break;
case 6: x = "Definitely!";
break;
case 7: x = "Maybe.";
break;
case 8: x = "I don't think so.";
break;
case 9: x = "I'd say no.";
break;
case 10: x = "Probably.";
break;
default: x = "Try Again.";
break;
}
System.out.println(x);
}
public static void main (String [ ] args)
{
Scanner scan = new Scanner(System.in);
boolean a = true;
while (a)
{
System.out.println();
System.out.println();
System.out.println("What would you like to ask the Magic Eight Ball? Make it a \"Yes\" or \"No\" question for it to work.");
System.out.print("\n\n--> ");
String what = scan.nextLine();
System.out.println();
Number();
System.out.println();
System.out.println();
System.out.println();
System.out.println("Would you like to go again? Enter \"Y\" for yes, and \"N\" for no.");
System.out.print("\n\n--> ");
String run = scan.nextLine();
run = run.toLowerCase();
if (run.equals("n"))
{
a = false;
}
}
}
} `
My dilemma is, I want all these methods being used the switch statement, the while loop but I want to replace the Math.random with the SecureRandom method how would I go about doing that?
I tried using the whole SecureRandom randomNumber = new SecureRandom(); to do it but it kept giving me errors that I could not convert secure random to "int".
You just need to instantiate a SecureRandom
object and use its nextInt()
method:
Random rand = new SecureRandom();
int magic = 1 + rand.nextInt(10);
