小明希望这次求雨的降雨量尽可能大，请问最大值是多少?

public class day06 {
    public static void main(String[] args) {
        //初始化降雨数组
        int[] rain = new int[49];
        for (int i = 0; i < rain.length; i++) {
            rain[i] = i + 1;
        }
        //每周施法的数组
        int[][] week = new int[7][7];
        for (int i = 0; i < 7; i++) {
            for (int j = 0; j < 7; j++) {
                if (j < 3)
                    week[i][j] = rain[i * 3 + j];
                else {
                    int i1 = rain.length - 1 - (i * 4 + 6 - j);
                    week[i][j] = rain[i1];
                }
            }
        }
        System.out.println("每天应抽的数字");
        for (int i = 0; i < 7; i++) {
            for (int j = 0; j < 7; j++) {
                System.out.print(week[i][j] + " ");
            }
            System.out.println();
        }
        System.out.println("七周每周产生法术能量的中位数");
        int [] week_day = new int[7];
        for(int k = 0;k<7;k++) {
            week_day[k] = week[k][3];
            System.out.print(week_day[k]+" ");
        }
        System.out.println();
        System.out.print("所以，最大降雨量为：");
        System.out.println(week_day[3]+" ");
    }
}
运行结果为：
