Make a diamond shape

Hi.....I am having problem on coding and make a diamond shape with 9 rows.
so, 1st row has 1 star, 2nd row has 3 star, 3rd row has 5 star etc...

I got this so far but just dunno how to continue:

             for ( int counter = 1; counter <= number; counter++ )
            {
                  for ( int side = 1; counter <= side; --side )
                        System.out.print( ' ' );
                                                
                        for ( int side = 1; side <= number; side++ )
                        
                        System.out.print( '*' );
                        System.out.println();
                  


                  }


Anyone can advise? Thank you so much! I am a beginner, so please be patient~

Hi!

I think this one is a homework.

Here are some tips for creating a diamond shape.
1. Create a loop for the upper half of the diamond. And then another one for the lower half.
2. The number of "*" for every row increments by 2.
3. The number of " " for the first row =  # of rows / 2 - 1 (The 1 is for the asterisk). Then for the upper half, it will decrement by 1 for the succeeding rows .
For the lower half, it will increment by 1.

I hope I helped.

easier if you do the top half 1st, then the bottom half, try something like:

for (int i=1; i<number; i+=2)
{
   for (int j=0; j<(number-i)/2; j++) System.out.print(' ');
   for (int j=0; j<number; j++) System.out.print('*');
   System.out.println();
}
for (int i=number; j>0; i-=2)
{
   for (int j=0; j<(number-i)/2; j++) System.out.print(' ');
   for (int j=0; j<number; j++) System.out.print('*');
   System.out.println();
}

When I modified mine to:
             for ( int counter = 1; counter <= number; counter+=2 )
            {
                  for ( int side = 0; side <= (number-counter)/2; side++ )
                  System.out.print( ' ' );
                                                
                        for ( int side = 0; side <= number; side++ )
                        System.out.print( '*' );
                        System.out.println();
                  }

            System.out.println();
            
            for ( int counter = number; counter >0; counter-=2 )
            {
                  for ( int side = 0; side < (number-counter)/2; side++ )
                  System.out.print( ' ' );
                  
                        for ( int side = 0; side < number; side++ )
                        System.out.print( '*' );
                        System.out.println();
                  }

It printed out...........

woops, should be drawing i stars, not number. that should be

 for (int j=0; j<i; j++) System.out.print('*');
