JAVA题目！！！急求！！！第一题：（本题40分）(a+b)的n次幂的展开式中各项的系数很有规律，对于n=2，3，4时分

import java.util.Scanner;
public class main {
public static void main(String[] args) {

System.out.print("Enter number from 1 to 10:");
int number = 0;
while (number!=-1){
number = s.nextInt();
generateSet(number);
}
}
private static void generateSet(int n) {
int[][] m = new int[10][11];
if (n==-1) System.out.println("Quit");
if (n 10) System.out.println("Error");
if (n == 1) {

m[1][1] = 1;
}
if (n >= 3){
