数组的总和和最大数

public static void main(String[] args) {
        int[] result = calculate(10,20,30);
        System.out.println("总和：" + result[0]);
        System.out.println("平均数:" + result[1]);
    }
    public static int[] calculate(int a,int b,int c){
        int sum = a + b + c;
        int avg = sum / 3;
        int[] array = {sum, avg};
        return array;
    }
