java打印金字塔数字

您好！欢迎与我对话。下面是Java打印金字塔数字的示例代码：

import java.util.Scanner;

public class PyramidNumbers {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        System.out.print("请输入金字塔的层数：");
        int n = input.nextInt();
        input.close();

        for (int i = 1; i <= n; i++) {
            for (int j = 1; j <= n - i; j++) {
                System.out.print("  ");
            }
            for (int k = i; k >= 1; k--) {
                System.out.print(k + " ");
            }
            for (int m = 2; m <= i; m++) {
                System.out.print(m + " ");
            }
            System.out.println();
        }
    }
}

您可以根据自己的需求调整金字塔的层数。希望对您有帮助！
