“缺少return语句”但我已经有return语句

Question

/*
 * One common programming activity is to find the minimum and maximum values 
 * within a list. In this challenge activity we will do just that. It will also
 * demonstrate how arrays and for loops compliment each other nicely.
 * 
 * First, execute the main() method as is so you can understand how the for loop 
 * works with the array.  If you must, set a breakpoint and step through the code.
 * 
 * Notice the min and max values are not correct. That's where you come in your 
 * job is to write these methods. Regardless of min or max, your approach should
 * be the same: (Here's the pseudocode for min)
 * 
 * set min to the value of the first element in the array
 * for each element in the array
 *  if the current element is less than min
 *      set min to the current element
 * end for
 * return min

我不断地得到缺少的return语句并且在解析时到达文件的结尾，然而我已经有了return语句并且我的代码正确地关闭了括号。请帮忙，谢谢

在getmax方法中，您会得到错误，因为如果(a<=max)则returnmax不可访问
