java打印10行杨辉三角形

好的，以下是Java代码实现10行杨辉三角形：

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] = 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 = 0; i < rows; i++) {
            for(int j = 0; j < i+1; j++) {
                System.out.print(triangle[i][j] + " ");
            }
            System.out.println();
        }
    }
}

输出结果如下：

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
