Java Programming Lotto Number generated

I don't know how to make a Lotto Program that you have to get 6 numbers out of a range of 1 to 49. None must be repeated.
Does anyone have a clue on how to achieve this? The output must be done 5 times in a row.

You want 5 sets of 6 randomly generated numbers like this:

1 22 33 44 55 66
2 23 23 42 23 1
2 33 23 42 23 1
2 14 23 42 23 1
2 3 23 42 23 1

If so that can be relatively easily done using a 2 dimensional array and a couple loops.

I assume you'll wanat to sort the numbers as well...
definately a good looping exercise...

JessieH, have you had a chance to try it yourself yet?
present us with some code and we'll be better off to help ya.

can someone help me with a personal project for the lotto
