Lottery number generator - Java Example

We generate 6 numbers out of 49 numbers. We have to check that a drawn number is not repeating all the previously drawn numbers. We sort the results finally.

You'll learn most by trying my code while watching the video.

Please post your improvement on my code on the comments.

Concepts:
do-while loop
for loop
Random class
Array

[leeeeooooon]

Thank you for the tutorial!! You do a great job in explaining each line of code.

[Ens_wei]

This is exactly what i needed, thank you.

[ayayay]

This tutorial was very useful! One question, what do you mean by indexDrawn?

[harrishenry]

Well executed coding.
Can you prepare program that produces random numbers based on input of previous winning numbers?

[prototipagemmecanica]

how can i list all possible combinations?
and of these possible how can I define a condition to eliminate them from these generated?

[wenkaiyang]

lotteryArray[k] simply means which slot it draws from 1 to 6 and not the number it draws. so how can it lotteryArray[k]== randomNumber?

How can I make a lottery program that takes 3 number from user and displays 8 random numbers (any range maybe 1-100). And tell what numbers from user matches the lottery numbers without using loops and arrays.

[sheldonwatt]

is there any way to make the code use methods like getNumber() to get the numbers and a method like sort() to sort them?
