编写程序打印帕斯卡三角。

//用户输入打印的杨辉三角的行数line,输出：打印杨辉三角（每个数字的宽度是4.）package printPascalTriangle2;import java.util.Scanner;public class PrintPascalTriangle2 {public static void main(String[] args) {Scanner console = new Scanner(System.in);System.out.print("input the lines > 1:");int line = console.nextInt();printNext(line);}public static void printNext(int line){//计算数值int [][]s =new int[line][line]; for(int i=0;i <= line-1;i++) {    for(int j = 0;j <= i;j++)     {   if(j==0||j==i)     s[i][j]=1;   else     s[i][j] = s[i-1][j-1] + s[i-1][j];}    } //打印  for(int i=0;i <= line-1;i++) {    for(int j = 1;j <= (line-i-1) * 2;j++)       System.out.print(" ");    for(int k = 0;k <= i;k++)       System.out.printf("%4d",s[i][k]);    System.out.println(); }}}//class
