generate an output pattern

Write a program that will display a pattern depending on n. Assume n as a one digit odd number.

Example: if n=9, display
*000*000*
0*00*00*0
00*0*0*00
000***000

How's about this? I believe it satisfies your requirements.

Not quite I don't think. If the pattern depends on n, it suggests the pattern will be different for different values of n, so I think the code should be

an example is great, but it isn't a spec. what EXACTLY should happen for various values of n?

On a more serious note
@chrstian Nobody is going to write the code for you (see NotACodeMill), but if you come up with a more detailed specification* we will certainly try to help you write the code.

* For example
How does that pattern relate to the value 9 ?
What are the patterns for other values of n ?
Is there an algorithm for working out the pattern given a value of n or are they just random patterns assigned to each value ?

Joanne, I think we are both correct. The behaviour for when n does not equal 9 is undefined so both of our solutions could be argued to be correct.

However, before we get off an a tangent, I threw in that somewhat glib response to highlight the fact that you have not specified your problem enough to be able to write a complete solution for it. A point that Fred has made in a more straightforward manner.

Another point to not is that we are NotACodeMill, which means that nobody is going to give you the solution. What we will do is help and guide you into solving the problem yourself. That's how we learn.

That's what I was trying to work out.

As far as I could see, each pattern is 9 characters long, and is made up of 6 '0's and 3 '*'s; but since 9 is the ONLY single-digit odd number that isn't prime, it doesn't seem to give much of a clue.

I certainly agree with your point, but it's actually kind of a neat challenge if you take it as one of those "intelligence test" questions.

My observations:
1. All patterns involve '*' and '0'.
2. All patterns are mirror images about a central '*'.
3. All patterns involve exactly one '*' in their "halves".
4. In order, they move from '*' on the outside, to '*' nearest the centre.

So my solution for n=7 would be:
"*00*00*"
"0*0*0*0"
"00***00"

and for n=5:
"*0*0*"
"0***0"

for n=3:
"***"

and if n=1 has a solution:
"*"

Anyone have a different solution?

cause i cant understant how the pattern generated , i believe this one can easily done by for loop thank you , i appreciate the answers i believe n=9 then system.out the expected output is not what im trying to explain but it's a valid answer due to not detailed question

thank you what im looking is a guidance not the exact answer

my bad not a detailed post , my post looks like im looking on exact answer

Well I'm afraid that's an absolute must. All I've been doing is musing about possibilities.

If this is for a class, then I suggest you ask your tutor, because what you've given us is definitely not enough to go on.

In that case it's not a Java problem, it's a logic problem.
And if that's all the information you have, then Winston's guess is as good as anyone else's. But for that matter, so is Tim's.
