java - 关于变量参数和匿名数组

Question

请告知如何将下面的程序转换为变量参数，这是java 5引入的新功能，现在我正在使用匿名内部数组..

public class AnnonymousArrayExample {

    public static void main(String[] args) {

        //calling method with anonymous array argument
        System.out.println("first total of numbers: " + sum(new int[]{ 1, 2,3,4}));
        System.out.println("second total of numbers: " + sum(new int[]{ 1, 2,3,4,5,6,}));

    }

    //method which takes an array as argument
    public static int sum(int[] numbers){
        int total = 0;
        for(int i: numbers){
            total = total + i;
        }
        return total;
    }
}

Answer 1

使用变量参数

public static int sum(int... numbers){}
