**一个方法可以有0,1，多个参数，但是只能有0或者1个返回值，不能有多个返回值，那我如何返回多个值呢？解答：返回数组**  
**下面举个例子，假如我要同时返回计算总和和平均数。**

public class Demo10ArrayReturn {
        public static void main(String[] args) {
            int[] result = calculateSumAverage(10,30,50);
            System.out.println("总和是："+result[0]);
            System.out.println("平均数是："+result[1]);
        }
        public static int[] calculateSumAverage(int a,int b,int c){
            int sum = a + b + c;
            int avg = sum / 3;
            int[] array = {sum,avg};
    
            return array;
        }
    }

**下面来解释一下**
