1.声明并初始化二维数组
int[][] yanghui = new int[10][];
2.给数组的元素赋值
for(int i = 0; i < yanghui.length; i++) { yanghui[i] = new int[i+1]; //2.1给首末元素赋值 yanghui[i][0] = yanghui[i][i] = 1; //2.2给每行非首末元素赋值 for(int j = 1; j < yanghui[i].length-1; j++) { yanghui[i][j] = yanghui[i-1][j-1] + yanghui[i-1][j]; } }
3.遍历数组
for(int i = 0; i < yanghui.length; i++) { for(int j = 0; j <= i ; j++) { System.out.print(yanghui[i][j] + " "); } System.out.println(); }
