一.題目

You are asked to create a method that accepts an array of integers and returns the highest value from that array.

(你被要求創造一可以接受數字陣列的，並回傳最大數字的方法)

Given the code fragment:

Which method signature do you use at line n1?

A. public int findMax (int[] numbers)

B. static int[] findMax (int[] max)

C. static int findMax (int[] numbers)

D. final int findMax (int[] ) 

二.答案

B

三.解析

建立一個方法，可以傳入int[]和回傳最大值，

findMax的參數是 numbers，那 numbers的型態是 int陣列，findMax的參數型態就是  int陣列，

findMax賦值給 keys，而 keys的型態是 int陣列，所以 findMax的回傳型態就是int陣列。
