创建一个奇数*奇数的二维数组，使其横竖斜相加都等于一个数

package com.sharp.servlet;

public class Test{
	public static int size=3;
	public  static void main(String[] args){
	
		int[][] arr = new int[size][size];
		int k =1;
		int i = 0;
		int j = (int)Math.ceil(size/2);
		while(true){
		
			if(i<0){
				i=size-1;
			}
			if(j>size-1){
				j=0;
			}
			arr[i][j] = k;
			if(k == size*size)break;
			if(k%size == 0){
				i+=1;
				if(i<0){
					i=arr.length-1;
				}
				if(j>arr.length-1){
					j=0;
				}
				arr[i][j] = ++k;
			}
			i--;
			j++;
			k++;
			
		}
		for(int m=0;m<arr.length;m++){
			for(int n =0; n<arr[m].length;n++){
				System.out.print(arr[m][n]+"    ");
			}
			System.out.println();
		}
