correction plz

-----------------------------------

i was wonderin if anyone could help in by correcting my code.... i am doin a program with will print out the following diamond pattern

y***** 
******* 
y***** 
yy*** 
yyy* (the y is a space) 

the thing is the middlw line the bolded line ... .. if the user inputs the size 5 (it should lok like the pic) themiddle line is always +2 ... mine gives an extra so it gives like 8 stars .... and i am able to remove sumof the lines above ....

import java.awt.*;
import hsa.Console;
public class Star
{
    static Console c;
    public static void main (String [] args)
    {
        int n = 0;
        int size = 0;
        int space = 0, star = 1;
        Console c = new Console ();

        c.println ("Please enter an odd number from the range of 
1-25");
        n = c.readInt ();
        space = n / 2;
        star = n / 2;
        while (space != 0)
        {
            for (int i = 0 ; i < space ; i++)
                c.print (" ");
            for (int i = 0 ; i < star ; i++)
                c.print ("*");
            for (int i = 0 ; i < space ; i++)
                c.print (" ");
            space--;
            star = star +2;
            c.print ("\n");
        }
         
        for (int i = 0 ; i < star ; i++);
            c.print ("*");                                  //middle 
line
        for (int i = 0 ; i < star ; i++)
            c.print ("*");
            c.print ("\n");
 
        while (star > 1)
        {
            space++;
            star = star - 2;
            for (int i = 0 ; i < space ; i++)
                c.print (" ");
            for (int i = 0 ; i < star ; i++)
                c.print ("*");
            for (int i = 0 ; i < space ; i++)
                c.print (" ");
            c.print ("\n");
        }
    }
}

I tried to help, but I couldn't run the program, cause 

import hsa.Console; 

I can't seem to import this, is this a standard thing that comes with JDK?
Im a noob, and I run java out of MS Dos prompt so...
I probably could help you a bit if I could run it and see what its like.

Help you with what and why did you post here in this thread?

-----------------------------------

well.. i've posted this before in some other thread.. but anyways..:

the for-loop draws out the lower part of the diamond. if u reverse the algorithm (which i haven't done) u can possibly create the upper part similarly


int w = 9;     // width of diamond

print    repeat " "  by  w - ((w - 2) mod w);  // might have to replace these
print    repeat "*"  by  (w - 2) * 2;          // three lines with better code
println;                                       //

for (int i = w - 1; i >= 0; i--) {
    print    repeat  " "  by   w - (i mod w);
    print    repeat  "*"  by   i * 2;
    println;
}


PS: note this is not valid java code.. just pseudocode. but you should be able to make sense of it
