Java：计算6x6宫格两对角线数字之和

计算如图的两对角线数之和 ，编写了一段较为简捷的代码

public class Training {
	
	public static void main(String[] args) {

        int [][] scores = new int[6][6];
		int num = 0;
		int sum1 = 0; 
		int sum2 = 0;
		for (int i = 0; i < 6; i++) {
			for (int j = 0; j < 6; j++) {
				scores[i][j]=++num;
			}
		}
		for(int i = 0; i< 6;i++){
			sum1 += scores[i][i];
			sum2 += scores[i][6-i-1];
		}
		System.out.println(sum1);
		System.out.println(sum2);
    }
}

输出情况如下：
