输出8行杨辉三角形java

以下是输出8行杨辉三角形的Java代码：

public class YangHuiTriangle {
    public static void main(String[] args) {
        int numRows = 8;
        int[][] triangle = new int[numRows][numRows];

        // fill the first column with 1
        for (int i = 0; i < numRows; i++) {
            triangle[i][0] = 1;
        }

        // fill the diagonal with 1
        for (int i = 1; i < numRows; i++) {
            triangle[i][i] = 1;
        }

        // fill the rest of the triangle
        for (int i = 2; i < numRows; i++) {
            for (int j = 1; j < i; j++) {
                triangle[i][j] = triangle[i-1][j-1] + triangle[i-1][j];
            }
        }

        // print the triangle
        for (int i = 0; i < numRows; i++) {
            for (int j = 0; j <= i; j++) {
                System.out.print(triangle[i][j] + " ");
            }
            System.out.println();
        }
    }
}

输出如下：

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
