可变参数的应用

代码如下：

package cn.yzx.day1;public class VariableParameter {   public static void main(String[] args) {      // TODO Auto-generated method stub      System.out.println(add(2,3));      System.out.println(add(2,3,5));      System.out.println(add(2,3,5,6));   }   public static int add(int x,int ... args){      int sum = x;      for (int i = 0; i < args.length; i++) {         sum += args[i];      }      return sum;   }}

运行结果：
