模仿c++同时处理多个

public class Test {

 public static void sum(int... num){
  int sum = 0;
  for(int i = 0 ; i < num.length ; i++){
   sum += num[i];
  }
  
  System.out.println("result is "+sum);
 }
 
 public static void main(String[] args) {
  //写法一：sum(1,2,3,4,5);
  //写法二：
  //int[] nums = {1,2,3,4,5,6,7,8,9,10};
  //sum(nums);
  //写法三：
  sum(new int[]{1,2,3,4,5,6,7,8,9,10});
 }
