Answer 1

 int n = 6;

for (int i = 1; i <= n; i++) {
    for (int j = 0; j < n - i; j++) {
        System.out.print("  "); // 打印空格
    }

    for (int k = -i; k <= i; k++) {
        if (k == 0 || k == 1) {
            continue;
        }

        System.out.print(" " + Math.abs(k)); // 打印数字
    }
    System.out.println();
