You can assume that every element in the array is a one-letter String, for example  String[] test = { "a", "B", "c", "D", "e"};   This method will count the number of uppercase letters from the set A through Z in the array,  and return that number. So for the example array above, your method will return 2.   You will need to use some Java library methods. You may need some methods from  some or all of these library classes: String, Character, Integer.   COMMENT YOUR CODE. As well as the tests, the instructor will also read your comments  to verify that you understand and can describe the code you've written.   */  public class Question_5_Count_Uppercase_Letters { public static void main(String[] args) { new Question_5_Count_Uppercase_Letters().countUppercaseLetters(); } private void countUppercaseLetters() { // You can call your new countUppercase() method with these example arrays.
