可变参数和 增强for循环

public class MultiParam {

/**

* @param args

*/

public static void main(String[] args) {

sum(2, 5, 699);

List list = Arrays.asList("1","2","4");

System.out.println(list);

//可变参数 可以直接传数组

String s[] = {"f","j","m","d"};

list = Arrays.asList(s);

System.out.println(list);

//传基本数组小心

int arr [] ={4,8,6,7,3};//Integer arr [] ={4,8,6,7,3};

list = Arrays.asList(arr);

System.out.println(list);

}

public static void sum(int... nums) {

// 可变参数 拿到的是 一个数组

int sum = 0;

for (int pername : nums) {

sum += pername;

}

System.out.println(sum);

}

}
