程序代码：

package Lianxi;

public class LianXi14YangHuiSanJiao {

    /**
     * @param args
     */
    public static void main(String[] args) {
        final int N = 10;
        int array[][] = new int [N][];
        for (int i = 0; i < N; i++) {
            array[i] = new int[i];//定义该层数组大小
            for (int j = 0; j <= i; j++) {
                if ((j == 0)||(j == i)) {
                    array[i][j] = 1;
                }else {
                    array[i][j] = array[i-1][j] + array[i-1][j-1];
                }
            }
        }
        //打印出数组
        for (int i = 0; i < array.length; i++) {
            for (int j = 0; j < array.length; j++) {
                System.out.println(array[i][j]+" ");
