Also I cannot get the Collections.shuffle() to work correctly does anyone know how to use this properly, Thank you

Answer 1

When you use the letter "i" for an array index without using the code tags, the forum interprets that to mean "start italic" and your code is mangled - converted to italic and changed.
Repost using code tags:

Put your code here
[/code]
This error
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 5means that an array index value is greater than the max value allowed for the array.
If you can't fix this, identify the line where the error is happening (it's line 5)
