Answer 1

public static void main(String[] args) {
int i, j, k;
for (i = 1; i <= 5; i++) {
for (j = 1; j <= 5 - i; j++)
System.out.print(" ");
for (k = 1; k <= 2 * i - 1; k++)
System.out.print("*");
System.out.println("");
}

for (i = 1; i <= 4; i++) {
for (j = 1; j <= i; j++)
System.out.print(" ");
for (k = 1; k <= 9 - 2 * i; k++)
System.out.print("*");
System.out.println("");
