Java编程利用数组输出杨辉三角（要求输出10行）

好的，这是 Java 编程输出杨辉三角的代码，共输出10行：

public class YangHuiTriangle {
    public static void main(String[] args) {
        int rows = 10;
        int[][] triangle = new int[rows][];
        for (int i = 0; i < rows; i++) {
            triangle[i] = new int[i + 1];
            triangle[i][0] = 1;
            for (int j = 1; j < i; j++) {
                triangle[i][j] = triangle[i - 1][j - 1] + triangle[i - 1][j];
            }
            triangle[i][i] = 1;
        }
        for (int i = 0; i < rows; i++) {
            for (int k = 1; k <= rows - i; k++) {
                System.out.print("  ");
            }
            for (int j = 0; j <= i; j++) {
                System.out.print(triangle[i][j] + "   ");
            }
            System.out.println();
        }
    }
}

运行结果如下：

                  1   
                1   1   
              1   2   1   
            1   3   3   1   
          1   4   6   4   1   
        1   5   10   10   5   1   
      1   6   15   20   15   6   1   
    1   7   21   35   35   21   7   1   
  1   8   28   56   70   56   28   8   1   
1   9   36   84   126   126   84   36   9   1
