Pascal的三角二维数组-格式化打印输出

在这里，我修改了您的代码，它可以完美打印ROW大小，直到控制台窗口限制的13倍。

import java.util.*;public class Pascal {     public static final int ROW = 12;    private static int max = 0;    public static void main(String[] args) {         int[][] pascal  = new int[ROW +1][];        pascal[1] = new int[1 + 2];        pascal[1][1] = 1;        for (int i = 2; i <= ROW; i++) { pascal[i] = new int[i + 2]; for (int j = 1; j < pascal[i].length - 1; j++) {     pascal[i][j] = pascal[i-1][j-1] + pascal[i-1][j];     String str = Integer.toString(pascal[i][j]);     int len = str.length();     if (len > max)         max = len; }        }        for (int i = 1; i <= ROW; i++) {      for (int k = ROW; k > i; k--)     System.out.format("%-" + max + "s", " "); for (int j = 1; j < pascal[i].length - 1; j++)     System.out.format("%-" + (max + max) + "s",  pascal[i][j]); System.out.println();        }    }}

希望这可能会有所帮助。
