Maybe something like this :O

Code:

public class Stars{ 
	char star = '*'; 
	char[][]st; 

	public Stars(int cnl1) { 
		st = new char [cn1][cn1]; 
	       for (int i=0; i < cnl1;i++) 
	    	   for (int j = 0; j <cn 1;j++) 
	    		   st [i][j] =star ;
	} 
          

	void starsShow() { 
	     for (int i=0; i < st.length;i++) 
	    	 for (int j = 0; j < st.length;j++){ 
	    		 System.out.print(st[i][j]);
	    		 if(j==st.length-1)
		    		 System.out.println("");
	    	 }
	} 
}

Not sure if you will get something like this(1 year has past when i done such programms in school, so i am not sure^^):

Code:

void stars(int n)
{
    String st = new String();
    for(int i = 0; i < n; i++)
    {
        System.out.println(st+="*");
    }
    for(int i = 1; i < n; i++)
    {
        System.out.println(st.substring(i, n));
    }
}

            {
                str += "*";
            }
        }
        return str;
    }

    public static String Amount(int amount)
    {
        return Lines((amount & ~1) * 2 + 1);
    }
}
