a) Write the method signature for an instance method named minValue, which takes as a formal parameter an array of int and returns the minimum value found in that array.



b) Implement the minValue method. Some or all of the values in the array may be less than zero, so your implementation will need to cope with this.



c) Implement an instance method named cumulativeSums, which takes an array of int as formal parameter and returns an array of int. The returned array should have the same number of elements as array passed as the formal parameter. Each element in the returned array should contain the sum of the elements in the formal parameter,up to and including the corresponding element. For example, given an array {1,2,3},the resulting array would be {1,3,6}, since 3 = 1 + 2 and 6 = 1 + 2 +3.



d) Declare and initialise an array of seven String values to contain the days of the week, starting from Sunday.-a）写的一个实例方法命名为MINVALUE作为一个正式的参数，这需要一个int数组，并返回该数组中的最低值的方法签名。



b）实施的MINVALUE方法。数组中的一些或全部的值可以是小于零，因此实现将需要应付这个。



c）实施的实例方法名为cumulativeSums，这需要一个int数组形式参数，并返回一个int数组。数组传递的形式参数，返回的数组应具有相同数量的元素。返回的数组中的每个元素应包含的形式参数中的元素，包括相应的​ ​ 元素的总和。例如，给定一个数组{1,2,3}，得到的阵列将是{1,3,6}，因为3= 1+2和6= 1+23。



d）声明和初始化数组的7个字符串值包含星期几，从星期日开始。
