Complete Challenge Program #1 (Rainfall Class) in Chapter 7, page 535. Be sure to complete the UML Chart first. I will not accept any assignments not accompanied with a UML Chart. The UML chart should take no more that 15 minutes. Hint for your Class: Initialize your rainfall array when you declare it. Ex. {2.4, 3.1, 7.8} You will need twelve items, one for each month. Your class should have one field, an array of doubles, to hold the monthly rainfall data. It will also have a constructor that takes an array of rainfall data (we talked about passing array objects as arguments) and copies that array into this field (we talked about how to copy an array). Other things to think about: How to sum an array? How to get the average an array? How to find the highest/lowest element in an array? How to return an element at a specific index of an array?
