{

int x = 1;

int increment_by = 2;

while (x > 0) {

// print spaces

int spaces = 4 - x / 2;

for (int i = 1; i <= spaces; i++) System.out.print(\" \");

// print asterisks

for (int i = 1; i <= x; i++) System.out.print(\"*\");

// end line

System.out.println();

// change width

if (x == 7) increment_by = -2; // reverse

x += increment_by;

}
