Vinnibabu,
Welcome to the Ranch.
We do not just hand out solutions. We would rather you try on your own and learn on the way. If you have seen the other posts, you will have noticed that people post their code and other people help them figure out what is wrong with it.
Coming back to your problem.
It can be analyzed as follows:
1) The first line contains 1 star.
2) The second line contains 2 stars
3) The third line contains 3 stars
n) The nth line will contain n stars.
As you can see there is a pattern here. The number of stars match the line number.
Now can you tell us how you will go about solving the problem?

another hint...
it's often a good idea to break the problem down into the simplest parts you can, get that working, and only then move on.
the first thing you need to do is figure out how to print one star on one line.
Once I got that done, I'd go back and look a the requirements. I need a way to print one star, a way to print 2 stars, a way to print 3 stars...
which all sound like the same thing...i.e. a way to print X stars. so, maybe try writing a method that takes an int as a parameter, and prints that many stars...
and then keep working from there...

There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors

Did you do it with nested for loops?
