Hey C.C, I have a minor small problem.

I have right now headache and can't think of a way to randomize a String array.
I just can't get it to work. I have like rewritten it over 9000(seriously I have done it like that). So my last savior is you guys. Care to help me out?

Thanks in advance :)

Edit: My array is build like this in a object... String[] s = new String[3];
s[0]="Test";
s[1]="This";
s[2]="Thing";
So anyway to randomize their position later?

Forgot to tell you guys...

By looking at this: Koders Code Search: Randomizer.java - Java I think your solution is in sight. If not, I will open up a development environment and test it for you myself :)

You are adding those strings to indexes of an array of strings. What are indexes represented by and what will nextInt() for the Random give you? Put two and two together.

It works as a charm, I even shorten it since most things were not needed for my little thing :), thank you.

So could you put your little thing code here; I really want to know how you randomize it.

I try and do it;

The code is here :

// Demonstrate String arrays.
import java.util.*;
class StringDemo {
 
  public static void main(String args[]) { 
	  
    String str[] = { "one", "two", "three" };
    
    for(int i=0; i<str.length; i++) {
    	
    	int n = (int)(3.0 * Math.random());

      System.out.println("str[" + i + "]: " +
                          str[(int) n]);
  }
}
}

[-xAsN]

in other words, use Math.random function to randomly select a number within the string, indicated by the [], thereafter displaying it via println. hope it helps!:)

Still, I got it fixed by using the advice Philip gave out, thanks again Phil!
