for (int c = 5 - b; c >= 0; c--) {
System.out.print(" ");
}
for (int a = 1; a <= 2 * b - 1; a++) {
System.out.print("*");
}
System.out.println();
}
for (int d = 4; d >= 1; d--) { //下部分
for (int c = 5 - d; c >= 0; c--) {
System.out.print(" ");
}
for (int a = 2 * d - 1; a >= 1; a--) {
System.out.print("*");
