You can also try this if it helps :)

Together it will make a pyramid structure

CODE:

pyramid() {
    for (int i = 1; i <= 5; i++) { // loop row
        for (int k = 1; k <= 5 - i; k++) { // 1st triangle (printing space)
            System.out.print(" ");
        }
        for (int j = 1; j <= i; j++) { // 2nd triangle
            System.out.print("*");
        }
        for (int l = 1; l <= i - 1; l++) { //3rd triangle
            if (i == 1) {
                break;
            }
            System.out.print("*");
        }

        System.out.println();
    }
}
