Pyramid Star Triangle with Astrik in Java

How to make a program in java to get a pyramid star?

The Program -

class PrintPyramidStar

    public static void main(String args[]) {

        int c = 1;
        for (int i = 1; i <= 5; i++) {
            for (int j = i; j < 5; j++) {
                System.out.print(" ");
            }
            for (int k = 1; k <= c; k++) {
                if (k % 2 == 0)
                    System.out.print(" ");
                else
                    System.out.print("*");
            }
            System.out.println();
            c += 2;
        }
    }
}

Now the best way to know how it works is by making some changes in the code. Lets do that.

 I will mark the changes I have made in the above program with red.

 CASE 1 -

class PrintPyramidStar

    public static void main(String args[]) {

        int c = 1;
        for (int i = 1; i <= 5; i++) {
            for (int j = i; j < 5; j++) {
                System.out.print(" ");
            }
            for (int k = 1; k <= c; k++) {
                if (k % 2 == 0)
                    System.out.print("1");
                else
                    System.out.print("*");
            }
            System.out.println();
            c += 2;
        }
    }
}

 That resulted in this 

    *
   *1*
  *1*1*
 *1*1*1*
*1*1*1*1*

Ah! So I guess it was for the free spacing between the stars/asterik marks.

Now What if we tweak the numbers.

  

Case 2

Assigning c =10; 

class PrintPyramidStar {

    public static void main(String args[]) {

        int c = 10;
        for (int i = 1; i <= 5; i++) {
            for (int j = i; j < 5; j++) {
                System.out.print(" ");
            }
            for (int k = 1; k <= c; k++) { 
                if (k % 2 == 0)
                    System.out.print(" ");
                else
                    System.out.print("*");
            }
            System.out.println();
            c += 2;
        }
    }
}
 

Output -

    * * * * *
   * * * * * *
  * * * * * * *
 * * * * * * * *
* * * * * * * * *

Got it?

Can you print this?
