    Default Re: random

    What class/object is holding the Strings?
    If an array, use one of the Random class or the Math.random() method to generate a number from 0 to the size-1 of the array.

    Norms idea is the best way if you are going to be using an array. Here is a quick example for you:

    public class RandomString {
     
    	/**
    	 * JavaProgrammingForums.com
    	 */
    	public static void main(String[] args) {
     
    		int rand = (int) (Math.random()*4);
     
    		String[] array = new String[4];
     
    		array[0] = "Java";
    		array[1] = "Programming";
    		array[2] = "Forums";
    		array[3] = ".com";
     
    		System.out.println(array[rand]);
     
    	}
     
    }
