在一個(gè)矩形中,只繪制它的對(duì)角線和左右兩條邊就能滿足你的要求.中間的三角形是實(shí)心的為了簡(jiǎn)單，所以行列都用奇數(shù)表示了（只有一個(gè)頂點(diǎn)嘛，^_^）public static void main(String[] args) {int row = 20; int column = 23;int min = Math.min(row, column); row = column = min % 2 == 0 ? min + 1 : min; int k = row / column; for (int i = 0; i < row; i++) {int cur = Math.round(k * i);int middle = cur - row / 2;cur = middle >= 0 ? row / 2 - middle : cur;for (int j = 0; j < column; j++) { if (j <= cur || j >= column - cur - 1) {System.out.print("*");} else { System.out.print(" "); }}System.out.println(); }}效果如下：* *** ***** ******* ********* *********** ************* *************** ***************** ******************* ***************************************** ******************* ***************** *************** ************* *********** ********* ******* ***** *** *
