Answer 1

Try this code:

I have changed the first loop:

for (int i = 1; i <= size-1; i += 2) {

---

int size = 9;

for (int i = 1; i <= size - 1; i += 2) {
    for (int k = size; k >= i; k -= 2) {
        System.out.print(" ");
    }
    for (int j = 1; j <= i; j++) {
        System.out.print("*");
    }
    System.out.println();
}// end loop

for (int i = 1; i <= size; i += 2) {
    for (int k = 1; k <= i; k += 2) {
        System.out.print(" ");
    }
    for (int j = size; j >= i; j--) {
        System.out.print("*");
    }
    System.out.println();
}// end loop
