Java打印杨辉三角形

好的，以下是Java实现打印杨辉三角形的代码：

import java.util.Scanner;

public class YangHuiTriangle {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("请输入杨辉三角的行数：");
        int n = scanner.nextInt();
        int[][] triangle = new int[n][n];
        for (int i = 0; i < n; i++) {
            for (int j = 0; j <= i; j++) {
                if (j == 0 || j == i) {
                    triangle[i][j] = 1;
                } else {
                    triangle[i][j] = triangle[i - 1][j - 1] + triangle[i - 1][j];
                }
                System.out.print(triangle[i][j] + " ");
            }
            System.out.println();
        }
    }
}

运行后输入行数，即可打印出相应行数的杨辉三角形。
