可变参数

找出最大数

public class T {
    public static void main(String[] args) {
        int max = max(3,4,6,1,3,6,7);
        System.out.println(max);

    }
    static int max(int... numbers){
        if(numbers.length == 0){
            System.out.println("无可变参数");
            return 0;
        }
        int result = numbers[0];
        for (int i = 1; i < numbers.length; i++) {
            if(numbers[i] > result){
                result = numbers[i];
            }
        }
        return result;
    }
}
