Generating Random Numbers

[enrique21]

Im trying to generate random numbers using the statement:

Random r = new Random(2);
for (int i=1;i<=18;i++)

but im having errors in my results here is my entire code so far:

import java.util.*;
public class Random4
{
public static void main(String []args)
{
Random r = new Random(2);
for (int i=1;i<=18;i++)

{
int n=r.nextInt(19);

switch(n)
{
case 1:
System.out.println("n is a multiple of 3");
break;
case 2:
System.out.println("n is a multiple of 4");
break;
case 3:
System.out.println("n is a multiple of 5");
break;
default:
System.out.println("Chill dude");
break;
}

System.out.println(n);




}
}
}

Whats wrong with it?

Hello, and welcome to TSDN. First let's go over a few basics that will help you get the help you need:

1. Use code tags please. See how right above me the code looks a little nicer, well when you post look to the right to a box that says "REPLY GUIDELINES" and it will explain to you how to use code tags.

2. When you mention there are errors, it's helpful to tell us what those errors are, because often this is the biggest clue to figure out what's wrong with the program.

On a last note, I'm not 100% sure but I don't know why you're setting the "seed" of your random variable to be 2 when you do "Random r = new Random(2)" (look at the documentation of the random class here: http://java.sun.com/j2se/1.4.2/docs/api/java/util/Random.html ).

That might be your issue, but then again I don't know what you want and what is showing up.

Good luck,
