I think you're looking to output odd numbers~

Try this:

for (int i = 1; i < 50; i += 2) {
    System.out.print(i.toString() + " ");

I think the program is supposed to output random numbers between 1-49 and all being unique.
Not sure though.

Actually maybe not.

Nevermind.

The series goes in this order, the numbers are from 1 to 50.

The incrementation goes like this, +2, +4, +2,+4, +2, +6 and so on. Hope this clears the logical part.

I don't know how to put the code for it.

The logic is, from the series from 1 to 100 remove all the 2nd numbers, i.e.
1,3,5,7,9,11, ......

From the remaining numbers remove every third number i.e.
1,3,7,9,......

From the remaining remove every 4th number i.e.
1,3,7,......

this way the logic will proceed....

Lucky numbers or not, I think we have to consider amitdhar the winner here.. And the prize is.. Sorry, no prize.. :(

Anyways, you use a boolean array[100], I'll use coffee..
