Howdy folks, Let's try this again. This is a small program which is "supposed" to generate 3 random numbers from 1 to 6, not allowing any duplicates. Then it should put these numbers into an array of TextFields. It compiles but gives an exception in thread "main" NullPointerException. I figure that there is a problem with one of the arrays, but cannot figure out what the problem is. Any help would be greatly appreciated. Thanks, Howard

Here is the code... It took me a while to remember that little thingy about arrays of objects being a little different. I've also modified the random number generation to be a bit more compact.

Thanks a lot, Mike. I won't have time to utilize your changes until tomorrow, but suddenly my headache is fading away. I'm not familiar with the Vector class so this method did not even occur to me. I guess I need to look up the API for it in order to learn more about the provided methods. Thanks again. Howard
