用Java输出杨辉三角

以下是用 Java 输出杨辉三角的代码：

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 = ; i < n; i++) {
            triangle[i][] = 1;
            triangle[i][i] = 1;
            for (int j = 1; j < i; j++) {
                triangle[i][j] = triangle[i - 1][j - 1] + triangle[i - 1][j];
            }
        }
        for (int i = ; i < n; i++) {
            for (int j = ; j <= i; j++) {
                System.out.print(triangle[i][j] + " ");
            }
            System.out.println();
        }
    }
}

希望能对你有所帮助。
